Best Pre-78 250's

This thread had a bit of info about '77 model 250 MXers. But why would you want a '77 CR250 Husky, when you already have a '78 model ? They are virtually identical bikes, except for the skinnier swingarm on the '77 and the tapered roller steering head bearings on the '78 frame. I would just look around for a '77 CR250 or 390 swingarm . I would be confident that the AHRMA historic (Pre '78) class would allow '78 Husky framed bikes, seeing as how '75 Maico frames fitted with a '74 and earlier 4 speed motor are ok for their pre '75 class.

That would be the best case scenario, but the motor is viewed as an upgrade, so no go in the Historic class for the '78 Husky 250CR.

Plenty of '78 Husky's racing pre'78 with '77 swing arms in Oz.

Not 250 HVA's with 78 cylinders .. there is a very visual difference..

No one has said it yet but, the RM 250 B was a very good bike back in the day and very popular.  Of course Suzuki superseded it by the RM 250C part way through 77 but it was basically the same bike with the RM 125 B forks and alloy swingarm on it.

In my opinion the RM 250C should be considered a follow on model for Pre 78.  When the 125 and 400 Cs were released late 77 or early 78 a new 250 was released as well called the RM 250C2.

Also the Maico AW 250 was a good bike also.

Kevin the 250 "B"  had better suspension, but the  "A" motor was the one to have ... more a works motor ( Rh )

Of course Suzuki superseded it by the RM 250C part way through 77 by it was basically the same bike with the RM 125 B forks on it.

Almost the same, they look the same, but they are not actually the 125 forks. I have both sets and 250C has longer sliders, longer damper rods and more travel than 125B. There's probably a number of bikes out there with 250C forks thinking they are the 125b ones because unless you you know the slider lengths and the different casting numbers on the sliders is easy to mistake the 250c forks for the 125b forks.

My favourite 76 RM250A

I had a RM250B back in the day, it use to SMOKE my mates 250A.

Yes Watto, '78 250 engines are easy to spot, not the 390's though. Plenty of '78 frames in pre'78.

Have not ridden a "B" to compare the two John. Unfortunately in the west there are only a hand full of pre78 bikes in our club (Classic mxwa), generally we have to ride in pre 85. I really thought the 75/76 /77 era was going to be popular but unfortunately it isn't over here. Anyway I have fun mixing it up in the pre85's.

I had a RM 250A in 76 and had a RH in 75.  I got the ride my old RH during 76 when the RM gearbox shit itself.  The RH motor was a lot better than the RM.  Anyway Mayfairs Suzuki swapped the destroyed RM 250 for a RM 370 A.  Now that was a great bike.  B Grade to A Grade in three race meetings.

Are you sure that is an "A"  the swingarm looks like a "B" and the forks are 125 B.

[shelpi]

got me self a gaggle of RM's 125B, 250B and 370B So that make me bia's  but any who, get ya suspension working proper and you'l luv it, on saying that see if ya can scab a few rides ona few mounts, youll know wich one is for you!

[micko]

Well, it started as an original 'A' your correct it has a couple of add on's  ?

Did anybody ride a 77 Maico over here, seem to lead and win a fare few races in the UK, so I would say they would be up there.
