does anyone know if the fzr400 swingarm is the same width as the fzr600? i think they are since guys use to swap out the 600 swingarm for a 400 one but i want a 100% true answer before i buy a 400 frame i found forsale.

also are the steering stems the same 400 and 600?

I can't verify the sterring stem....but I can measure the 400 swingarm width for you tonight

Please do...fzr400 frames with titles expensive so i prefere not to blow a ton of coin if i can't use my hybrid stuff on it.

i think the steems are the same...i remeber some member put yzf600r front end on them, i just need a 100% true answer.

Yeah I was under the impression the 600 stuff went right into the 400 stuff

I can meansure the steering stem tube as well that will get you a rought estimate!

I am more concerned about the swingarm fitting int. i know the dimension of the fzr with out the dust caps is 8.47" if the 400 is the same i can do what i thinkg i may want to do.

rdzombie currently has an 89 fzr600 swingarm on his rz500/fzr400 hybrid , fits like it was meant to be there . he also has an r7 front end with an rz500 stem , which takes the same bearings as the fzr400 and 600 , it also bolts on like it was meant to be there , you should be fine .

What parts are interchangeable with the FZR400?
The following parts will interchange between a 400 and a 600:

rear wheels (if you use the caliper hanger that goes with the wheel)
front wheels (as long as the rotors/calipers go with their matching forks)
complete front ends (triple clamps are the same)
motors (with the change of a few things - see 600 motor swap)
handle bars and levers
gas tanks (the 600 has a slightly higher filler neck, but fits every where else)
switch gear and throttle (cables differ at carb)
foot pegs and levers
clutch cables
swing arms
rear shock and all linkages
carbs (may need jetting change)
front brake calipers (only applies to '88-89 400's and pre 4-piston 600's)
rear brake calipers (all)
front and rear axles
rear gas tank brackets
regulator (Sloan's says the part number is 1 digit off, but this has been tested in racing circles)
radiator fans
radiator caps, (Quoted from an anonymous source - If the price of a new Yamaha radiator cap makes you choke, go to your local auto parts store and buy one for an '89 Honda Accord. It's the same.)
thermostats
gas caps (Note, the filler neck on the 600 tank is taller)
ignition switches
sprocket covers
starter clutch covers
starter relays
cam chain tensioner
turn signals

so will an aluminum rear brake tensioner arm off a 400 bolt on to a 600?

aluminum rear brake tensioner will work. The FZR600 swing arm will work on the 400 frame too. They are the same width at the swing arm pivot.
