YZ465H, YZ250H differences
« on: September 30, 2011, 07:45:53 pm »
Would someone be able to tell me what the differences in chassis and swing arm are between a 465 and a 250 please. I intend to change mine to a 465 from a 250. Thanks.

Are you sure I thought they were exactly the same  :-\

The only triple jumps he would have been doing are the hop, skip & jump.

just checked the yamaha bible the 250g has the shorter swingarm ,the h frame on both 465 and 250
have a steepend rake by 1 degree compared to the g but they both have the longer swingarm.
i havent actually tried the shorter swingarm now that i have found this out i probably wont be as my frame is a h

Fair enough.
As far as the roller goes I think they are identical ... almost.  The 465 has different handlbar mounts (rubber mounted).
Everything should bolt straight in if you are doing H for H.

Most people take off the headstay anyway.  The jury is out, but I've been told it causes the barrel to crack  :-\.
