Excellent! I have started doing an ad hoc version of gymkhana on my TDM. It stemmed from teaching my gf low speed skills on her DT & I enjoyed that so much I had a crack at it on Tubby. I do need to get some engine bars, though, had a couple of heart in mouth moments.
I set up our course with half tennis balls, easy to ride over & I put in a stop box to practice our braking in a turn.
I've gone from crapping myself doing a u-turn in 8 mtrs of road to doing 360's in less than 5 mtrs & figure eights from full lock to lock. The training has made me a lot more mobile & confident on the bike. It also really emphasizes that you go were you look even if it's over your shoulder.
Gymkhana has just started to happen down here in NZ so hopefully I may be able to enter an event in the future.
