For those who are looking for just a little more. Our 260 Swing Arm Kit has been specially designed to handle Metzler's 260/40/18 tire. (Will also fit Dunlop's Elite 250 & Avon's Venom 250 tire). Our swing arm modification is done with strength and rigidity in mind. Our design makes the bike look like it should have come from the factory that way and not like you just made a bigger tire fit. Give your bike the big tire kit it deserves. Rear wheel retains its original tracking position.
