single swing arm variant or mod to fit other bike swing arm?

mod ah..

use superduke ponya

Bike review : CFMOTO 800NK. Currently mileage 1400km. Owned for 1 week.


Reason I have chosen the bike.

1) Excellent price to performance
2) Tech
3) "Fully loaded" Bike (Cruise, damper, connectivity, quick shifter)
4) exhaust note
5) Fun engine
6) Looks. yes, it does look damn good, any case better than the KTM sibling which it shares the engine and front half of the frame..


Good
Powertrain
To me the KTM 799 middle weight twin engine may be one of the best out there now. The torque response is very linear and pulls strongly from 4000 rpm with an additional kick at about 6500rpm and continues to pull strong to redline (9500rpm) . Top speed is around 220km/h and it takes very little effort to get there. Cruising rpm at 130 is around 5000rpm@6th. But as the motor spins up really fast, sometimes I have caught myself looking for the missing 7th gear. The gear shift action is short and precise. The standard quick shifter (when working) is fast, able to bang upshifts and downshifts smoothly and quickly with the exhaust giving you a nice "brraaap" on the upshift. You will still need some clutch action to smoothen out 3-2-1 downshifts. Sometimes, the engine management gets confused and blip the throttle too much on the downshifts at the lower gears leading to some surging. I'm getting about 200-250km cruising range from around 12L of fuel, which isnt too bad. Whack it all the time, and I've emptied the tank in 100. The tank holds 15L but light comes on with about 5L remaining (this doesn't sound right)

The exhaust note is fine fine fine. This is one bike you wont be tempted to get an aftermarket rear can off the bat. Nice burble and pop on the overrun. Nice fart on the upshift. Gotten many good comments from other bikers. Many not suspecting it is a stock can.

Handling and brakes
Handling is relatively nimble and sure footed. Bike is eager to turn. You can slide from the seat side to side fairly easily, basically supporting your weight on the pegs. Grip levels are generally hampered by the budget Maxxis Supermaxx ST single compound tyres. While dry grip levels are good, it doesnt communicate very well, so it saps a bit of confidence on lean. Plus with no T/C on the bike and a punchy throttle, one needs some extra caution getting on the power coming off a lean. Had some minor tail slide that was easily caught during my shakedown runs. Granted, I was also scrubbing in the new tyres. Will test these out again when the bike is repaired.
The bike setup from the factory was a little stiff for my weight, so I will likely do another shake down run after turning down the preload and rear rebound. Can feel the rear tyre skipping a bit too much on rougher roads. The tyres are hard so I will likely play with the tyre pressure as well for further finetuning. But this bike needs better rubber to shine. (the maxxis are also standard on the KTM790)

Brakes are powerful, although feel is lacking. But I shall reserve judgement until I put a few more miles on it as i think the brakes haven't been fully bedded in yet. It has a total of 10 brake pistons on the bike, which is commendable, and the rear brakes is quite good. It has twin 4 piston radial J Juan calipers clamping down on twin 320mm cross drilled floating discs and a twin pot sliding caliper on the rear. ABS action is good. Front lever is a radial master. Both clutch and brake levers are adjustable for reach. The front has a lot of stopping power and ABS doesn't kick in too early. The rear in particular is good. Allows for a bit of locking before working, so you can back the tail in a bit before the rear ABS corrects.

Comfort
The bike is set up with more relaxed ergos than the KTM sibling, similarly to the MT09. Clip-ons are fairly upright and foot pegs are in the mid position, far less tucked up as you would be on a Z900. Where the KTM puts you perched high in an attack position, and the MT09 too upright, and the z900 sits you "inside" the bike with the unnecessary low seat and high pegs, the NK strikes a good balance.
The mid peg position however, occasionally gets in the way when you want to get your feet down, having once snagged on my pant leg and gave me an "oh shit" moment. Seat height feels more like 820mm compared to the 795mm it was advertized with. So, if you have a short inseam, you might need to tippy toe a bit. The seat at the crotch is narrow and helps with those short of leg.

Aero at 130 is pretty decent with not much buffeting and air pressure on the chest....possibly due to the big TFT acting as a wind deflector. It starts getting a little uncomfortable at 150, and you better hold on tight at 200, even in a full tuck.

Vibrations at speed are not perceptible but there is an annoying buzz in the mirrors past 7000rpm.

Cruise control works great. Holds speed well. However, it only works from 80-130kmh and only in 4/5/6th. But any cruise control is godsend for long cruises as it allows you to rest your throttle hand.

Seat comfort is a miss. The padding while firm, is supportive in pretty much only one position. So unless you fit the ideal rider triangle (which I guess is of a larger rider), your bum would be at the wrong place. Cant seem to get past 1hr ride without getting numb bum. Maybe seat needs more miles to be broken in. The rear pillion seat is not for human use wan. Utterly useless or as contraceptive. very hard and in all the wrong shape. Must as well been a single seater.
Rear brake and gear shift lever is adjustable for height and reach.


Tech
The big TFT is gorgeous. Although it does catch the sun and reflects it back to your face. The system also allows you to hook up 2 bluetooth helmet sets, so you can have rider/pillion com without buying expensive coms. Having a pillion at the back is another issue all together.
Bike comes with full LED lights. The front is decently bright, but the cut off is very abrupt. Would have preferred a more gradual cut off. The little light dance on startup is a definite attention grabber.




Bad
Reliability and build quality remains a big question mark (just look at the section below). The unpainted plastics feel a bit cheap and doesn't look like it would hold up under long sun exposure. The paintwork on the tank is quite soft. But hey, this is not a 80k bike...you get what you pay for,
As a new bike, while Taobao has most spares and accessories in the market, some parts like windshields and luggage/racks are still a rare find. For windshields, the few on the market are for the Basic model and not ours with the larger TFT, so they would not clear the TFT. It might still need a bit more time for them. Whether you want to depend on MFORCE for parts is a question I hope I don't have to ask.

No Android auto. While the TFT supports Apple carplay, Android users are left in the cold, only supporting screen mirroring. The included Carbit Map is a subscription service (first year free) but the interface is very slow and choppy. Google Maps, Waze works hell a lot better. You will need to turn on your phone's hotspot for it to go online. The bluetofsh audio coming off the bike is also oddly softer. Not figured out why yet nor tried another bluetooth headset with the bike.

No USB charger. For a bike this loaded, They decided to skimp on the USB charger??. Fortunately, you can buy original PnP solutions from shopee or taobao for around 80rm. And it does quick charging.


Problems.

It seems that CFMOTO is still struggling to work out build quality issues and QC from this first batch bikes. Been in touch directly with Mfroce service and CFMOTO marketing.

Issue 1 : The rear hugger was not installed correctly, with the bolts not threaded through the frame of the rear hugger. So within 20kms of picking it up from the shop, it came up and contacted the rear wheel, causing the rear hugger to be eaten up, necessitating the whole assembly, signal lights and harness to be replaced. This has serious safety consequences, as should had the hugger come loose and gotten caught in the wheel, it would have thrown me off the bike.










Issue 2: Cone bearing failed at 1100km after my shakedown runs. Whole front end is rocking back and forth

Issue 3 : The quick shifter mysteriously stopped working completely for a day. After letting the bike sit for 3 days, it decided to work again. It wasnt a wet day when that happened, so that rules out a water induced short.

Issue 4 : Very bad partial throttle fueling/mapping. Very jerky holding throttle steady at 5-10% around 3000-4000rpm either in low speed or cruising. No solution to that yet. I remember the Duke 790 had the same issue but a subsequent engine map update sorted it out. Hope is CFMOTO will be able to roll out an update soon. Rain and Steet mode numbs the finicky throttle a bit, but still present. But why buy a 800cc bike for it to feel like a 650??

Issue 5 : Some bolts have backed out and loosened. Primarily the front sprocket cover which was making an annoying racket.

Issue 6 : axle/axle bearing over greased. Causing it to flow/fling down to front brake disc. Lucky caught early or it would have ruined/glazed by brand new brake pads....or cause a crash at worst.




MFORCE

For the rear hugger issue, The Dealer (GScycle) got an immediate authorization from MFORCE to tow the bike back to GSCYCLE service, and strip off an existing new bike for parts. The bike was towed from my house at 7.30pm, and the bike was ready to be towed back to me by 11am the next day. All warranty claims were done by GSCYCLE so it was fairly fuss free for me.

For the cone bearing issue, MFORCE service requested that the bike be sent back to Penang. They are in the process in arranging a loaner bike for my use in the meantime. However due to the CNY break, that process has taken longer than i had thought. Segambut CFMOTO doesnt have a loaner on hand, so they had to get penang to ship one down, as luck would have it, i was told it needed to get "repaired" before they can ship it down. Thats unfortunately not very confidence inspiring......... but i'm appreciative of them actually checking the bike before sending it to me. I supposed they would be able to send the loaner down in a day or 2 more and pick up my NK to be sent back to penang for the repair and once over...looking over every screw and bolt. How long that would take/taken will be updated here later.


FWIW, i applaud the various personnel for being responsive to my issues. I'm pretty sure they are aware of what a PR nightmare this could be for a new brand. Granted, the CNY break did slow things down a bit but this is something I would update later once the issues have been fixed.


Would I recommend the bike? Perhaps. Maybe wait for later batches? Once they sort out the build quality? But as she stands it would be tough to find a bike that is this fun for the money.



Immediate Ccomparisions would be the Suzuki 8s and the Kawazaki z900. The NK sounds better than the Suzuki, pulls harder, but lighter and nimbler than the z900. Ultimately, you wont go wrong with either 2. A KTM Duke 790 similarly equipped would be north of 85k OTR.

Nicely written.
mforce needs to take notes, how are they releasing their premium brand with lemon qc

Yes, exactly. I firmly believe CFMOTO can make good bikes (after all, it makes the sister duke790 for KTM). Who dropped the ball was MFORCE. This would be a litmus test for them.

They screw this case up. They will be forever tarnished. I think a lot of people will be looking at this and see how MFORCE handles this.

There has been a few cases of bad build quality from people I know. Pity they were too silent.

Does anyone looking for CFMoto 800Nk Service Moto? Can go to

Shopee Link Here

most important.

is the wiring diagram clear? or high res enough to see all the details..

if you can provide a screen shot of a section of wiring diagram in 100% magnification, will be good.

example...

100% magnification to large but this pdf is super clear!

Certainly felt like this when I tested the 8s.

After 8k rpm, it just feels the ECU is limiting power for whatever reason, while the NK (and 790) pulls strong to redline. That's one of the reasons I went with the NK. It also pulls harder throughout the entire rpm range.

Just to update.

I sent in my NK to Mforce Segambut SC on Friday morning 23/Feb. MForce Penang said Segambut will do the repair in order to avoid delays shipping the bike back to Penang.

The suddenly Segambut says they are shipping the bike to Penang to avoid delays getting parts. WTF.

So the bike sat at segambut for a week with nothing done and was finally shipped back to penang Friday 1st march.

Looks like segambut and penang playing football...with the expenses of the owner.

This seems what most owners faced when sending bikes to segambut. Sit there for a week or 2, then only decide to send back to penang, and then sangkut at penang for another few weeks...and then wait for transport to ship it back down again.

Just for this reason..I think anyone should avoid any MForce bikes if this is the after sales they intend to provide.

wah even hq play taichi.. find third party pomen also cannot

Just to update. More MForce foibles....


As the bike was sent back to Penang, I told the service manager to also change the oil and do the break in service.

When I got the bike back, I noticed the service indicator was still on. Called and asked why wasn't it SOP to reset the service indicator after the service.

Lo and behold, the service manager told me they had forgotten to do the service and shipped the bike back without it because they were concentrating in trying to investigate the quick shifter issue.

They did put 200kms on the bike testing it (which was fine for me) but didn't find out anything wrong with the QS. But when I got the bike back the QS started intermittently not working again. (So wtf did they try to check?)


It wasn't until a few days of riding later when I discovered the shifter lever is loose. The shifter bolt has gotten loose and backed itself out. Tighten it back up with loc tight. (Funny MForce didn't discover this the 2 weeks they had the bike)

Now it seems the QS is working again..but will have to give it a few more riding days. The guess is the loose and vibrating shifter might have caused the QS sensor to mis-read and go into safe mode.


Even doing the shifter bolt is a real PITA. Have to take off the foot peg assembly to get to the bolt (screwed in from the back and not front like typical japanese bikes) so it required an impact wrench to open for the big bolt holding the foot peg assembly...not something you can do roadside if it happens again...say in the middle.of a road trip....Real WTF.

factory saving cost... cant buy loctite

on a serious note hope everything is fine now with your bike.

Just to do a quick update on the bike.

Bike just turned 15k on he clock.


The bike remains as fun as expected. Nimble enough to have fun in the twisties and responsive enough to get the front wheel up without too much coaxing. Not really missing the lack of TC. Top speed is somewhere north of 220. Perfectly acceptable for a naked bike. Bike is comfortable cruising at 130-150, save for a bit of handlebar vibration at around 5000rpm. Otherwise vibration isn't bad

Ergonomics is fine. Sitting triangle is fairly upright and not cramped. Good for 3-4 hr rides having taken the bike north over the border last month. The seat has soften out a little after broken in. However if you are bigger or heavier set guy (I'm 5'6" and 63kg), you will likely appreciate the optional thicker seat.

Worn out the factory Maxxis Supermaxx ST tyres after 13k, and now have a set of new Michelin PR6.

Maintenance hasn't been too expensive. A standard oil change filter change ranges from 300 to 400 depending on what oil you choose. Takes 2.9L of 10w50 fully synthetic. Factory OCI is 15k, but I change mine every 10k. Major service and VC inspection is every 30k.

Parts availablity is good on taobao. But don't depend on MForce.


Reliability/issues
QS still has intermittent problems. But it looks like the issue is if the bike was started in gear, where the weight of the bike is on the gear (like on an incline) the QS does not work. If the bike is started in neutral and the gearbox is free of load, the QS works. Probably due to the gear position sensor. But it does not happen often so I just let it be.

Paintwork on certain painted parts isn't holding up well. Some items like the bar end weights have worn out. Not a huge issue anyway since I have replaced them with higher quality and heavier bar ends

What about wind protection after you've added the windshield?

It's still a rather small windshield. Takes wind off your chest but your shoulders and helmet still gets the brunt of it.

However, that said. If you tuck down, you can just get the helmet under the wind blast for a top speed run. It's a naked bike afterall. You will get lots of wind. But cruising at 130 to 150 isn't too bad for a few hours ride. The stock aero isn't too bad to begin with.

There is a bigger handlebar mounted windshield available for our NK but I don't like how it's mounted. Looks like an afterthought. Mine looks like OE that came with the bike

As for mods. Not much has been done to it yet. Still rocking the stock exhaust which is pretty good sounding anyway.

Bar ends
radiator guard
Frame slider
Custom windshield
Fog lights with custom harness and fuse/relay box

The stock steering damper is from WP..albeit a fairly basic non-adjustable unit.

can share the link of your windscreen ?
