Not been riding my 4RT for 3-4 months and went out to re-try a few sections that I did, at a recent Trial, that I cleaned on my other 2T bike Tried on the 4RT and would it grip, no it bloody wouldn't - even with a brand new tyre............. on muddy hillsides and woodland type sections Grr, I find the front end has a mind of its own sometimes too Rocks, fine Streams fine Mud/Banks..........nope
