I bought a used set of forks for $50, but after getting them home, I realized that they are a larger diameter than the ones on my '85 V-Max. What year did they change to bigger forks and since I have the upper and lower clamps, could I just replace all of it? is the head of the frame different? Has anyone done this?

Thanks in advance for any help. P.S. - I won't actually be doing the work on my bike for a long time... higher priorities.

The 43mm Forks came up in 1993. They came along with 4-Piston Brake Calipers(different Mounting Distance, bigger Rotors (298mm instead of 282mm) and a different Fender Bracket, but lost the Air Connector underneath the upper Fork Yoke.

If you have those Parts also, is's a direct Swap. Not sure about the Collar on the right at Wheel Axle. You might check this in the Parts Catalog. Steering Head, Bearings and such stayed the same.

You never cease to amaze me Squeeze, what a wealth of info you are! Thanks
