Interchangeable Parts

[Mike_Ham_250R]

I have a few questions on interchangeibility...

1. I hear the 250r/400ex bolt pattern is the same correct? (also interchangeble with the 350x/200x)
2. Does a TRX250R Shock fit an ATC250R?
3. Does a TRX250R swinger bolt right up to a ATC250R?

heres your answers

1---the rear wheel bolt pattern is the same on all 4 bikes you mentioned. the 83-85 200x wheels you have to run them backwards on the 250r's and 350x's.

2--- the trx shocks will fit the atc's no problem but the remote resivior hose is a about 5" longer on the trx250r's

3---the 86 atc250r swingarm is exactly the same as the 86-87 trx250r's. you can put a 85 atc one on a trx if your really desperate.

So a 86-87 swinger WILL NOT fit on an 85 ATC250R?

the swinger will fit, but be prepared to use a complete 86 atc or trx rear end...brake caliper, sprocket, brake hub should be the same, carrier, and i think axles too...
