CBR 250 RR, and CBR 250rj, difference

[nudemetalz]

Well I can remember riding the first model CBR250's (MC14) when they first came over here (Jap-import) in about 1990. Came away mighty impressed that a 250 four-stroke was this fast and very smooth too.
Not quite as quick as my '86 GSX-R400 at the time but lovely bike to ride.

Gear-driven cams = no more Honda cam-chain tensioner problems.

Cheers

I've had both a MC19 and MC22 and the 22 was a lot quicker and smoother. Braking and handling was also improved, although they are a bit heavy for a 250.
Get a two stroke 250 they're a lot faster

Well heres the whole CBR250 chronology:

MC14 (CBR250 FOUR)
Actual mopels: CBR250FG & CBR250FG-YA: Both '86
45hp, twin font disks, bikini fairings, single head light, very high final gearing

MC17 (CBR250 R)
Actual models: CBR250R(H): '87
Same as above, but full fairings with slight changes to everything, lower final gearing.

MC19 (CBR250 R)
Actual models: CBR250R(J): '88 and CBR250R(K): '89
Twin head lamps, Bigger single front disk, fuel pump (no gravity feed), motor with more torque @ lower rpms. Still 45hp though. The RK is first CBR250 with speed limiter.

MC22 (CBR250 RR)
Actual models: CBR250RR(L): '90, '91, CBR250RR(N): 92,93 and CBR250RR(R): '94-'96. Anything after 96 was built in 96 and labelled the RR(R)II.
Totally changed frame. Bent swing arm, Back to small twin front disks, gravity petrol feed. Speedo cable from back sproket, siz spoke wheels. The RR(R) is now limited to 40hp (restricted in head and ignition - can't be removed).

Tidbit: the 18,500RPM redline is a myth - the revlimiter kicks in at 17,230rpm.

are you sure dutch?

mines an 88 CBR 250 single R hurricane an has twin front discs yetis an mc14.

You never want to encourage a new rider to get a fast bike. Causes many troubles up to and including death.

Good to see that arguments whilst both parties agree, can still happen.

wtf?

i do not agree you dumb ass

if you look under 88 it says MC19

and the rev limiter doesnt kick in at 17 an a bit. there is none

so i do not agree. i disagree.

He never mentioned anything about being a learner.......

[BNZ]

Any ideas on why they decided to lop 5 HP off? Was the bike getting a reputation as a 'widow-maker'?

Law restrictions? Same as the *cough* 200kw *cough* limits on jap cars.

[joel]

so are you saying that he 1987 cbr250r hurricane doesnt have a rev limiter

[FlyingDutchMan]

I'm 100% sure. If you take the pillion seat off, there is a sticker on the sub frame informing of the model bike you have and the orginal paint code. As for the rev limiter - it exists alright - I've bench tested it with accuracy down to 0.1RPM, and highest revs I managed to get any spark signal out of it at all was 17,232 RPM.

Mikey: You do NOT have a 1988. Sorry, but if its got a twin disks/single headlight and full fairings its an 1987. If its got bakini fairings its an 86. Your pic doesn't have side fairings, but is that cause they've been removed or it is an 86?

Seems there is quite alot of difference between the bikes,
my MC19 only had a single disk and was no where near 45hp, i had it dyno'd when i got serviced and it was only making 33hp,
I didn't test the redline limiter but i had a speed limiter at 180kms (thanks to a big hill) when it sat on 16500rpm and wouldn't go any further

The 45 is the factory quoted power at the crank. Dyno measures power at the rear wheel.

Like SPMan said...crank power vs. rwhp.

mine only ever made about 30 I think...so you got a good one...Sniper says his MC22 makes 40+ I think...which is impressive (and rare).

[N4CR]

Not much difference - both hondas so they just suck at different levels.

Only real way to compare these figures is on the same dyno on the same day (or close enough). I wouldn't be suprised if it was between 33-37 on the 'arse baron' dyno.

I did find out why it makes that much for a 250 though. And I aint telling
