i just put one on last friday that i got from RM for a 2000 cr 250, dosent leek but its a little tight going on and off, but the more you work it the better it goes, its like cutting the edges of the treads a little each time but it works fine and looks good.
I ordered a trick polished billet/anodized black cap today out of Tucker Rocky for a CR 250. Its backordered until April 13th but when i get it ill let you guys know how it works.
