CBR 250 RR, and CBR 250rj, difference

[GNR]

hey

besides from things like, year, and mc number, what are the differences in these bikes??

both as relible as each other?
which one is faster, by how much, aprox?
better handlin?

just as many facts as your know

Cheers Heaps, brook

[TwoSeven]

The RR isnt a year designator - its the model. There was an R (single R in the late 80s) and a RR (double R) in the 90s. rj is a year code.

If you want to get the low down on cibby 250s go to the jdm forums - they have all the stuff there.

http://www.cr-x.org/cbr250/

[GNR]

yer i know the RR has nothin to do with year, i ment, like, are the preatty much theyt same bike, excepte it was called an RJ in the earlyier years or somthing?

Is the RJ model the race one as well, like the RR ?

[k14]

U didn't listen to two seven. There is no such model as the CBR250RJ, there is a CBR250R and CBR250RR. The RR came out in 1990 and replaced the R. The CBR250RR(J) is just the designator for the year it was made, all pre 94 CBR250RR's are the same (paint changed sometime), after that they are restricted to 40hp.

[HDTboy]

R's have single front disc and quite a different looking frame to the RR's. I've never ridden an R myself so that's all i can offer

[Mr Skid]

Is the RJ model the race one as well, like the RR ?Buy a R(J) model and put it in a race. It'll be a race bike then.
Why would you want a race bike to learn on anyway?

Do you really need to ask???:devil2:

Never heard of an RJ. I know I ride an RR.

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.

[GNR]

hey, thanks for the posts, sorry two seven, got a bit confused:D,thanks for clearin it up k14.

Mr skid, I was just intrested to see if it was a race replica, or whatever it is, If if it was just a single R

Don't the '90-'93 RRs have 45hp, and then the 40hp law came into force in Japan in '94? As far as I know, I have the '92 L model. The colour of mine is supposed to be the '92 colour scheme (colour NH-237P)

And the rev limiter didn't stop it going past 20k when I found false neutral :crazy:

Yeah. I learnt something last night. Only the J and K models have the single disc. The CBR250R single headlight models both had dual discs up front. Weird that they changed to a single for a couple of models :oi-grr: .

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

[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
Chris

[SimJen]

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 :)

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

[mikey]

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.

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?

Download the manual: http://www.cr-x.org/cbr250/forum/topic.asp?TOPIC_ID=23215&whichpage=3 (scroll about 1/2 way down the page). There is also links to the parts manuals.

[Damon]

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.

[Sniper]

I did find out why it makes that much for a 250 though. And I aint telling :2thumbsup

[TwoSeven]

No,
The '92 MC22 is capable of 45bhp rear wheel with jetting and pipe. I ran mine at 40bhp using a pipe - didnt see the need for jetting.

The stock pipe and jetting runs the bike between 35bhp and 38bhp depending on which MC22 you have (you tend to get 38ish if you have the 520 chain conversion).

33ish would be about right for an MC19.

The MC19 has a very slightly torquier (4%) engine, and produces the same power as the MC22 engine (45), but at lower revs. I dunno why people think the MC19 has less. The MC19 also has its ignition retarded between 14,000 and 16,000 rpm so that it complies to the japanise law of 45hp. Advance that back in line with everything else and it'll go over 45 easy.

[N4CR]

Can you do that stuff to a ZXR, or not because are they just too cool already.......

Mine was 35.7ps with an aftermarket pipe and jetting/carbs that need adjusting (we all love idling at 2k :|).

I've only ever seen dyno charts for them in the mid 30s in stock form. Not seen one putting out more than the later model (although I am aware they did go backwards on the very late models).

With the CBR250's getting on in years there is quite a spread in power outputs based on wear and tear alone, my old MC19 I'd happily say is in the high 30's bone stock, based purely on how it can still get to it's speed limiter with my 110kg lump on top of it.

Used to feel fast, until I bought the YZF :banana:

[FlyingDutchMan]

I've seen you in person man! If you're 110kg stock then I'm a fucken metric tonne - and I still beat XR8s at the lights!

Ya know when I saw you last - the prob with my bike was that it had hydrolocked. Same fucken thing this weekend! Sat morning was... (man where is the strike through?) would have absolutely beautiful to go out to akaroa and come back this morning. Alsa! My bike had other ideas. :mad:

Actually I'm 111.5kg, confirmed on three(one analog, two digital) seperately certified sets of scales at my work :2thumbsup Muscle is much heavier than fat, and I've been lifting pig iron for almost a decade now :banana:

Isin't there something on cbr250.com about the carbs that causes the hydrolock issue?

I know what it is in my case - the tanks rusting from the inside out and all that shit occansionally causes the float valves to be stuck open :doh: Should really do something about it some day.

I can't imagine you being that heavy - you didn't look that big! What would your bike have though.. with two of yous on there??

[2wheels in Red Beach]

2wheels - you have the original CBR250R, single headlight models came with twin fronts, yours must have been just before they released the twin headlight model in '88

[FlyingDutchMan]

I have a 88 CBR 250R with twin front discs.

If your bike is the one in your avatar, then its an '87 - the CBR250R(H). Look on the frame on the right side near the steerin column and the number will be between MC17-1000006 and MC17-1025449. If you lift up the pillion seat and look on the subframe there will be a sticker saying model: CBR250R(H) and have the colour code: NH-196 (may have No.6 with colour code).

[2wheels in Red Beach]

It does say MC 17 but cant find the sticker.

[mikey]

engine will say what ever has stamped into it. twin discs means twin discs. single headlihgt means single head light. not much in it. if your really worried lose some wweight you fat cunts or ride it like you stole it.

The engine number always starts with MC14. Heres a picture that I made up a while ago that'll let you very quickly identify your CBR250 (if its got it original paint scheme - otherwise it may take a little longer). http://middleparkmanor.homeip.net/pictures/cbr250s.jpg

from 1992 & onwards they only have 40hp here's the proof

http://www.motorcyclespecs.co.za/model/Honda/honda_cbr250rr%2092.htm

I have the 1991 model which redlines at 19,000rpm but the max toque is at 12,000rpm & max hp is at 15,000rpm. Mine also has a chipped ecu modified carbs & modified airbox & a carbon fibre racelines exhaust which will have about 50hp. Goes quiet well for a first bike.

Well that site is wrong - they're confused between the years. Download the CBR250 service manual and check it out for yourself: http://www.ravemasta.com/~crxorg/CBR250ServiceManual.pdf

And my tacho (the original honda one) recons my bike revs to 19,000 as well. Except I've actually measured it, and it is only 17,230. Don't put too much faith into dials and gauges. How well the bike is tuned makes a HUGE difference to its performance.

EDIT: I should warn you... the manual is 216MB big - right click and save it straight to disk.

[justsomeguy]

How well the bike is tuned makes a HUGE difference to its performance.

Could you please elaborate on this.

What would you do to a CBR to make it a bit quicker.

[FlyingDutchMan]

Could you please elaborate on this.

What would you do to a CBR to make it a bit quicker.

Well if its poorly tuned, it can bog down, have flat spots, jumpy through the rev range etc... You tune it well, and it'll pull smoothly all the way to the rev limiter. And hitting the rev limiter should feel like hitting a brick wall. If it doesn't yourbike isn't tuned to the best performance.

To make the bike quicker than stock, well you'll have to give it a nice exhaust, perhaps the whole system, re-jet the carbs. If you want to further, get a new ecu made up (one without a speed restrictor), slap on a turbo, fuel inject it, etc.... your wallet is the limit really.

Getting rid of the speed restrictor is piss easy - cut one of the wires (the right one!) and attach it to another through a 5cent resistor. Done - no need to buy speed de-restrictors off trade me... they're just preying on the gullible. I saw one on there for $150 :eek5: Thats one huge arse mark up for a 5c resistor in a little plastic box with a couple of wires and two plugs.

Interesting info on what a speedo de-restrictor is: http://www.cr-x.org/cbr250/forum/topic.asp?TOPIC_ID=22334

And one last note: having a wheel tensioned chain (1" slack) and well lubed does make quite a difference to the performance.

say bikesRus import a 2003 fireblade today. they dont register it as a 2006. it gets registered as a 2003. unless ltnz or bike shop fuck up / try decieve customers.

What do you mean when you say tune?? What is involved ? I don't know much bout mechanical stuff...

I don't want any speed de-restrictors..... don't want to blow anything up.

My bike will pull strongly till 160 anyday. Then go uptil 175 if I want it to. I don't want to go any higher.

It's doing about 15-16Krpm at 160 and around 16-17krpm at 170ish. Thats as fast as I'll let the little motor go.

I'm more curious on what you mean by tune rather than anything else.

I usually ride out in the country somewhere and only care about quick throttle response not top speed.

I don't want any speed de-restrictors..... don't want to blow anything up.

My bike will pull strongly till 160 anyday. Then go uptil 175 if I want it to. I don't want to go any higher.

It's doing about 15-16Krpm at 160 and around 16-17krpm at 170ish. Thats as fast as I'll let the little motor go.

I'm more curious on what you mean by tune rather than anything else.

I usually ride out in the country somewhere and only care about quick throttle response not top speed.


Ahhh..... i see you want to learn about the dark art of carb tuning. I don't really know enough to provide any advice, but this thread: http://www.kiwibiker.co.nz/forums/showthread.php?t=25560 seems to pretty good. Just add a few 1000 rpms onto his numbers.

Well most probably the weekend of the 18th or 19th March (I prefer Sunday the 19th) depending on when the other 4 riders I want to call and you are free - will PM you the details.

Yup a lot closer to your driveway (22).

jsg i think flyingdutchman is referring to making sure the bike is running sweetly, not so much 'tuning it up' as far as modding it is concerned.

Have a good read through that aussie CBR forum, they have lots of mods you can do on there to affect lots of different aspects of the bike.

Saw one of those repsol replica CBR250RR's today... to be honest it looked stupid, not enough noise to live up to the paint job :zzzz:
