Differences between RM250A & B ?

[John Orchard]

Hey Guy's,

I'm toying with the idea of rebuilding an RM250A but I always wanted (again) a 250B, what are the differences between the two?

Would a 125B swingarm bolt into the A?

I think this link to two article will tell you all the differences.  It wasn't just the swingarm.

Look at the left side under RM250 and click on Magazine Articles.

125B arm wont bolt into a 250A 125B arm is way smaller .

Some of the differences off the top of my head betweem 250 A and 250 B are bore and stroke ,Cyl head , chamber, muffler, air box , swinging arm , shocks, forks , shock mount position , front number board , Cdi ,seat , brake pedal, front axle , rear axle ,  Early A models have different tank , kickstart and shaft , magnesium rear hub.

Kinda like a phuket t shirt, "same same, BUT DIFFERENT"

The main similarity is that the paint colour has the same colour code I believe

I forgot Crankcases, gear lever, carb, some gears , shift forks ,throttle cable , stator /rotor , rear sprocket, and early A rear gaurd  must be getting old 

But of course in true Suzuki form 99% of the parts are interchangable

The main difference on the track is the long stroke motor and box section swingarm of the B. It has better power than the A and improved handling.

Ha ha, wow thanks, hmmm I remember back in '77 my mate had an A, it never went as good as my B, now I know why  :-)

John find or borrow the Suzuki parts book for A and B (and S ,X etc ) as it has a lovely supplement with picture details of the various different parts for the models!!!!! Yes I have one. Tim754
