My major service cost (Triumph Tiger 850) at Fast Bikes:

Own engine oil
Own oil filter (Triumph ori RM88)
Own drain plug crush washer (RM10)
Own spark plugs (CR9EK x3 RM79)
Own cam seals (Triumph ori x6 RM252)
Own brake fluid (Mannol 3002 DOT4 Synthetic RM19)
Own drop-in K&N filter (forgot how much I paid for it, RM350 incl shipping I think. Original Triumph paper filter is RM250, so the K&N will automatically pay for itself at the next major service)
Quoted labour charge for major service RM425.
Misc parts (cam cover seal, gaskets, o-rings, but new shims not included) RM340.
Since they still keep stock of the original Triumph HD4X HOAT radiator coolant, I'm asking them to do a coolant change as well. That's gonna be extra. Actually, coolant change isn't due until 30,000km, but I just want fuss-free riding & commuting until I hit 50,000km. Just oil & filter changes until then.

Brake fluid needs to be changed as per schedule. My front pads are now down to 25% after 22000km. New Brembo 07BB37LA sintered pads for both front Stylema calipers come up to RM450 incl shipping, will change after I pass the 25000km mark together with the tyres. Thinking to mount the new Michelin Road 6s. With my chain oiler keeping the chain lubed every week, I expect the chain & sprockets to last until 50,000km. Will also add HEL braided brake lines at that point, plus the forks will need to be serviced too by then (fresh oil & new seals). So the next major expense will be at the 50,000km mark, which is a good 2.5 - 3 years from now.
Overall, the bike has been pretty much problem-free since I bought it new in Q4 of 2021. I mostly use the bike to commute to work and touring trips with the wife every now and then. Only 3 small niggles so far - squealing rear brake (stone debris jammed in the rear brakepad), engine warning light came on briefly 3 weeks ago (water fouling the O2 sensor, no biggie) and the steering head may now need a little tightening (handlebar shimmy at low speed when hands-off, not noticeable with hands on the bars).

In comparison, my wife's CFmoto 700 CLX which is near the very end of its warranty at 20,000km has had its O2 sensor replaced after several trips to Mforce (error code showed up), plus 2 weeks ago it mysteriously died without warning and left her stranded on her way to work. Thank goodness for Allianz Road Warrior. Bike refuses to even crank since, just clicking sounds but no crank - we suspect it has something to do with the ignition relay or worse. Mforce had the bike sent to Penang for dunno how long coz they can't figure it out, so we're looking around for a replacement bike since it's too fucking tiresome having to deal with Mforce which is only open on weekdays and strictly during office hours.

So far the Trident is at the top of the list coz the CB650R continues to be plagued with stock problems until mid next year and the upcoming 2024 model arriving end of next year will no longer be priced competitively (Honda privilege, plus the unnecessary expense of that e-clutch bullshit). New SV650 stock has arrived, but it's kinda hard to justify coughing up RM39k for a bike that is way too long in the tooth and the wife found the wooden plank seat uncomfortable for her chinese arse. The GSX8S trades blows with the Trident esp with the current RM5k discount off the list price (RM50k), but ultimately we find that 3-year zero cost maintenance package of the Triumph too damn hard to ignore given that my wife will be racking up mileage like fucking crazy (Hulu Kelang - Pulau Indah commute).

Except for the first 1000km service (which was free coz I got a RM500 voucher when I bought my bike), I have always brought my own engine oil to Fast Bikes. Which is why I keep going back to them, esp now that my warranty has expired. I dunno about Goh Brothers though.

One thing to remember is that with the new Triumph models post 2021, you can no longer reset the service reminder (spanner icon) yourself... unless you buy a very specific Bluetooth OBD dongle and pay $30 yearly for the TuneECU app. You have to go back to the dealership to get rid of it, even when out of warranty. I have no issue with it though, coz it's reassuring to know that only trained people touch my bike and they put genuine stuff in it.

The Trident triple will never be the screamer that the CB650R inline 4 is. It's just physics. I used to own a 400cc inline 4 back in the day and that thing just had to the thrashed above 6000-7000rpm all the time, because the nature of inline 4 is that its power is almost always heaped at the top half of the RPM range. If you like high-revving engines and like to squeeze every last horse out of the engine when you ride, this one's for you.

The Trident is a little different. If you compare the dyno charts below (rear wheel hp & torque, unlike the manufacturers' spec sheet numbers that are measured at the crank), the biggest diff is in the fact that the Trident's triple lets you access almost 100% of its torque from 4000rpm onwards. The slight hole at 5000rpm is probably to meet emission requirements. The CB650R only hits 88% of its torque at 5000rpm, with a bigger hole at 6000rpm before matching the Triumph in power and torque at 7500rpm. Its horsepower advantage over the Triumph only comes after 8500rpm.

With the Triumph giving easier access to its full potential, it suits my wife for the kind of riding that she does. It might not suit you though, if you enjoy thrashing a screamer down the road when you ride. But that's as far as we're able to compare, because a CB650R demo bike simply doesn't exist.

If you're willing to take the Honda's premium pricing, you might also consider the GSX8S with its introductory discount. No replacement for displacement! But then, it isn't a screamer either with its 270-deg crank parallel twin... but from what I hear it's a fun torque monster. And, knowing Suzuki, it'll probably stay current for the next 6 years before they introduce an improved model lol. The only other option for you is then the Z900 non-SE at RM44k which represents a ridiculous amount of bang for your buck. If you want screaming performance, it blows every fucking thing in that price range right out of the water.

Can't say for sure, to be honest. The CB650R goes all the way to 12000RPM (being an inline 4 with a shorter strike, it's probably eager and able to), but in reality there's nothing left to give past 10,000rpm coz the horses trot downhill from there. It might be the same for the Trident, and if it too goes downhill past 10000rpm then that might be a good place to place the limiter to avoid overstressing the engine.

Your service intervals are interesting. Why is it due for service every 3 months? If you go by mileage instead, will it void the warranty?

Fast Bikes charged RM425 in labour for my major service which includes the VC, although the cost of the gaskets etc ended up doubling that number. Usually manufacturers would issue a service kit for major service jobs that includes all the various gaskets, seals and other knick-knacks required to do the job properly, so you might want to ask them if there are parts involved or do they skimp on these things (the "boleh pakai lagi" approach).
