Differences 78 /79 CR 250

[William Doe]

Probably been asked a 100 times before 

What are the major differences between a 78 CR 250 and a 79 CR 250 ?

If a club ran a Pre 79 class would the 79 model be considered a flow on ?

This is a hypothetical question so i dont need under MA rule 1235556667 

thanks

Bums on seats Bill .... bring it and let them ride it. My answer is yes

[William Doe]

Thanks Stu i would for sure , im just curious what the differences are though ?

The lower fork legs have a different axle clamp, sidecover stickers & slightly different front sprocket cover are the visual differences

Thanks Smed

mainly cosmetics as SMED has said - chain rollers also different - nylon as opposed to steel - not much at all really Bill - would definitely qualify as a flow on.

From memory, the '79 had an aluminium ring/spacer on the airbox around the airfilter to carb boot. I had a look on the parts book, but can't see that showing up on it though. I know that my 79 had the aluminium ring on it's airbox.

aftermarket part - still available

Yep, Rosco is right,  MotoX-Fox air box ring, not original

If you can get hold of a parts book it identifies the differences for the 1978, 79 and 80.  The Honda-Elsinore website has a download I think that you ay be able to get.

78 are thicker . Marty Moates LOP  bike ran 79 cylinder with 78 reeds for more rpm

Different in the barrels, 79 smoother power than 78... neither have great bottom end power but fun bike to ride.....
