I've enjoyed my '12 for 700 miles so far. Wings can w/ noise killer, stock map & air filter. Runs like a champ, no stalling whatsoever.
Only problem I've had was a leaking rear shock which I took to the dealer for a rebuild.
Oh yeah, and had to replace some rear light wiring that they managed to pinch & cut while they reinstalled the rear shock at the dealers
Riding this bike is so much fun it feels somehow illegal.
