40mm forks

Before I pull the trigger I would like to verify with you guys.

79 CR 25 MM frame....will a set of 81 40MM forks and triple clamp bolt right up?..Front wheel also?

thanks
Bob

Yes any frame with the tapered bearings in the neck the newer tripple clamp with the 40mm forks fit right in. If your using the 40mm front wheel your ok.


I purchased all disc brake 500cc front forks for all my builds.

With a little work you can fit a 84" set of 40mm on a ml frame to.

You made a spacer ?

Yes Michel i had a shim made for the top and bottom bearing cups the O.D. of the shim fits cup and the I.D fits the steering stem.I tig welded the shim to the cup so it cant fall out as that could make for an interesting ride.

So i will need a later model front wheel also?

if your going 40 mm you may as well get a twin leading shoe brake and wheel on it

if you have no class restrictions, you could go disc, 85-86 were marginal, 87-88 were much better
if you have class restrictions, unless they are hard nose you could probably run the twin leading

Will my current 79 front wheel work?

Yes

I purchased all newer front 40mm disc brake forks with the master cylinder, hose, caliper and disc brake rims. Might as well be safer.
