I can't comment on valve clearance, but R25 definitely has cheaper parts compared to Ninja 250. Generally, Yamaha spare parts are among the cheapest.

Kawasaki parts, at least in my experience, are more expensive. But nowhere near conti-brand bikes obviously.

Like any bike, it highly depends on riding style. If you're the type that like to terbang at redline all the way, then you'll most likely run into more wear and tear issues. What I do know is that the VC interval for R25 is short at every 10k km...not sure about the new model.

There are at least 3 Malaysian motovloggers who use the bike and they have a lot of experience. The ones I remember off the top of my head: Razrig, ARMI Motovlog and JaribR25. The first one has clocked over 100k km on his 2015 R25, and he has a bunch of videos on the maintenance required. I recommend checking them out.

Gotla.. Just not much coz r25 is more hyped up over the ninja making the r25 having a bigger market share so more coverage

This dood has owned his ninja for quite some time already. Theres also JD Motovlog but i dont watch his.

Theres also a couple of newer motovloggers with the newer ninja

Ninja parts are generally more expensive than r25 but they tend to last longer n more reliable.

If ur considering between the 2, thr ninja gets my vote... Proven reliable over decades and if any issues exists, its been around so long edi that solutions are available

Cakcibor uses the new Ninja 250, which I see some being sold second hand already.

IIRC, the bike had chain tensioner and throttle position sensor issue.

typical issue with the ninja 250 and z250 would be the coil.. brand new will be about RM1k from kawa (while R25 coil is about RM400). but u can get it recoiled for about RM400. supposedly better n longer lasting than ori kawa coz it uses thicker cables. this is a common issue with almost all bikes including the r25 as well as bigger bikes though.

my z250 started to have coil issues at around 75k km mileage.

just install a cheapo voltmeter to identify it early and u can get it fixed before it starts affecting ur rectifier. which is what i did... the voltmeter really helped... so i got it fixed before i got stranded anywhere.

other common issues with the ninja.... errr..... none that i can think of.

actually when it comes to reliability among the 250s....

i feel the order is...

1/ Honda CBR 250 (mainly coz i have never heard anything about it good or bad)
2/ Sym T2 (im in the FB group, with not much ppl asking about problems)
3/ kawasaki 250s (the twin pots, not the single pots)
3/ R25

the other 250s have their common plagues, which i would stay away from as some are catastrophic while some are simple but very tedious issues that can leave u stranded unexpectedly.
R25 has way more accesories though coz of all the hype and also the market share.

good thinking of getting used. so just buy the bike u like the most... as long as u make an informed decision, u will be prepared for any issues that may come.

Yup.. I meant pistons/cylinders

Parallel twins... Wont sound good with any exhaust hahahahaha

Yeah, the bike was from the first batch in Malaysia. The TPS issue also plagues some Ninja 400 according to the one Malaysian review from Borneo region.
Do you recommend installing the voltmeter before the warranty period is over? Any cutting of wires required?

I'm interested in installing one to keep an eye on my battery, but was worried about having to cut wires.

Damn connecting rods bruh
If you getting used, I strongly suggest additional 3k to rebuild the whole engine just because fuck Yamahai/Yangmahal

If you don't think that's sensible, and since you prefer ninja, just go for that instead.

I recall something about a rusting fuel tank cover for those models, but beyond that my knowledge is limited. They are generally quite reliable, even as workhorses. I see quite a few from 2014 (the green special edition) in my area with that sweet sounding Arrow exhaust. 
Yeah, this is also something I considered. If it's difficult to remove the Kawi 12v socket, I'll opt for this.

The Ninja 400 also comes with two more available bullet connectors in a loom under the rear seat, which is a third option that can be used.

Yes My R25
[attachmentid=10312799]

Between RM5 to 9k damage depending on options/availability

20k km mileage and only 2 years ownership
6 months of that duration wasn't even riding at all cuz hospitalised.

Personally for me, if I ever planning to get a kapchai i would rather buy it in cash instead of loan. Some kedai forces you to take AEON mia.

If higher than 250cc then i would consider opting for loan. Unless gaji 5 figure then shouldn't be a problem lah kot if you wanted to buy cash.

That's pretty normal...

If go watch movie how? need to hold popcorn and drink also 

so im gons start my lessons soon, gona get myself a bike.... realize i cant deal with the weight of the 6xx+cc bikes, so gona start with a 250cc

anyone have any comments on the r25 or ninja 250? its real odd that the used ninjas seem to go for slightly less than the r25 given they cost more new
any known big issues with the r25 aside from the numerous recalls?
i also hear kawasaki parts might cost abit more than yamaha bits? this true?

haha, wont cry if drop... that's what I had in mind

but is like that, many bikes are heavy getting off the side stand
so need to think how not to let it lean too low, and then drop it
and if that happens, learn to let go, coz bodily injury cannot be fixed, such as pulling a muscle or breaking a knee cap

- don't launch a bike with steering senget, it is possible the engine stall, mati, then bike can drop ( some ppl do this U-turn, risky)
- when turning, don't brake to a stop suddenly (it's easier to manage/balance a walking bike than a dead stop one)
- always make sure bike is steered straight when launching and stopping
- in the mind, remove the thought of having the backup plan to balance the bike with your feet down, this is a wrong safety net. I always try to balance a bike until I can stop it and put my foot down.

going to R25 can learn some technical skills first, but cannot get used to the weight yet
so... no right way to learn, just be safe

remember one thing, the learning school don't expose new riders to road riding, riding on main roads, with cars, buses and other vehicles
this is one thing fresh riders don't realize after getting lesen, they took the bike on to road, and then suddenly panic

which is why I think, personal opinion, don't jump on big bikes and get on the road without prior experience
having to handle an unfamiliar machine on our roads is quite stressful

Good find, and yes, it shows that I'm not the only one with issues with how he does things. Feel bad for those people who were just asking him questions only to get yelled at. Not a good attitude for a teacher to have, at least in my opinion.
I think he comes across as being too preachy and sometimes comments on things he doesn't understand because of where he is based. For example in the CSI style videos, UK, EU, Asia road rules are different from the US and I noticed he did, sometimes, try to blanket-apply US laws to all the videos people submit to him from all over the world.

Basically everyone has issues, but some people just have more issues than others. That being said, I know some people who are perfectly find watching MotoJitsu because they find that it's easier to take in the lessons he teaches. There is nothing wrong with that as long as we come out of it as safer riders.

in US alone, some states allow lane splitting, some states doesn't require helmet
even they themselves don't know everything

they should at least come here and blow their minds

True.
And one more you forgot - common sense.  In which even some of the experience riders are lacking.

Example
  You may have good skills and experience to squeeze in between two moving vehicles / lorry.
But common sense will tell you it's not worth the risk.  Just wait for another few more seconds to get a safe pass
