Should bolt right up the triple clamps '02 and '03 where 46mm, not sure about the front brake mounting...should.

I am 90%+ sure they will slide into your existing clamps with no issues.

i'd go with the ohlins,i don't think there was a whole lotta differences in the 03 compared to the 02 yamaha forks? my suspension tuner in joisey is a ohlins rep he'd do ya right on a rebuild/revalve:thumbsup: didn't they switch to nissin calipers in 01?

I will give you what I can in the way of the dimensions of the caliper mount points after I get home today. Watch this space after 6:00pm PST. I think they are the same, but I'll look at mine for you.

96-03 YZ forks are interchangeable.

That will bolt on.

The '03 fork does indeed fit. Tried the fork on an '01 wheel and it correctly bolts the caliper in position over the rotor. Whatever the change was, it was not to the mounting dimensions.

02 is the first year of the wider front hub. Thus the spacers are different from the previous years.
