yep I'm with Bill, replace your clamps with TM250 items or have your 125 clamps reamed out to 35mm and the options available multiply 10 fold. I run TM250 lowers with mid 80's DR250 internals and another has XL250 honda forks and both work a whole lot better than the 30mm spaghetti forks they came with
a little note also, RM80's had 30mm forks, though a little longer the lowers swap over but unsure of performance as I never ridden the bike that has them fitted
