I thought for 23 buck im going to try it. just bought a 2014 ktm 300 xc and these fit in the 4cs forks just great. done in seconds. no modifying. Make sure its snug but not to tight so you rip the o-ring. i can see how this would happen, where the stock screw you get on the bike it covers the o-ring where this product doesnt quite cover it 100% so u see mabye a half a millimeter or less of the o-ring but still is sealed. the number plate keeps that part of the bike really clean anyway. plus these sit lower than the handle bars so the shouldnt be in the way.
