trickedcarbine Posted March 27, 2017 Report Share Posted March 27, 2017 That's a lot of swing arm for a 421 cub. You may be hard pressed to get much input on what tire will work with that arm as most fellas will be running a little different swing arm.

J-Madd Posted March 27, 2017 Report Share Posted March 27, 2017 Wheelie bar or no? What kind of surface? What are the fast guys running where you ride? I could tell ya what I'd run at the track or where I ride in the sand once every 10 years. 14 pdl 72 roll out. Quote Link to comment Share on other sites More sharing options...
