Why the difference?

[buzzawak]

The US fzr(400 & 600) all use the same fork tube 1988-1996 except one, the 1992 fzr600RDC.
Would anyone know how the 1992 fzr600RDC fork tube is different?

Maybe it's a FZR600R DC .... it's a foxeye 600 with the 4JH engine. Those tubes are 41mm whereas the other 600 uses 38mm

Found a pic of the rdc. The RD has the 38mm forks and the "c" is the California model
Gee, Yamaha does some funny things

I think it was exup'd

up :)

so the 600 fzr and 400 fzr forks are the same?
the 600 fzr upper T can fit the 400 fzr fork?
because LSL does a nice superbike kit for the 600 FZR, and if it could fit the 400, i'd have the weapon for twisties

Forks come in 2 sizes 38mm or 41mm. £8 is generally the FZR600 and up to and including the 3en1. 3en2 and FZR600R (thunder cat and Fazer 600 are 41

3TJ's are 43mm

I think LSL will make clip-ons for all 3

No, FZR400 1WG 3EN1 forks are 38mm, but they take a smaller 282mm disc so the calipers sit lower down the leg. 1WG 3EN1 forks are 41mm and take a 298/300mm disc so they will fit the FZR600R 4JH but you'll probably need the wheel and spindle too as (I think) the 3EN2 uses a 15mm spindle whereas the 600R uses a 17mm one.. FZR400 3TJ forks are 43mm and take a 298/300mm disc but the caliper bolt spacing is 83mm... None are interchangeable without other parts as well, except the 600R and 3TJ front wheels.

As for the top yokes being the same, it's a case of buying one cheap and seeing if it fits...

Guy, please don't get confused. FORK TUBES, not the whole fork assembly are the same except on all US 400 and 600 except the 1992 FZR600RDC.

No, the stanchions are all 38mm but differ in length between the 400 & 600. The fork tubes or outer tube or the bottom bits !!
