Yeah, I had an R3 (sold it to my buddy and then I bought a track R6 which I promptly crippled by disabling a cylinder). He's now replaced/upgraded the suspension with aftermarket shock and fork cartridge kits (the stock suspension is pretty trash and sprung for a 140lb Indonesian adult), a slipper clutch (like all of the competition comes with standard, sigh), and a better front brake.
Small bikes are fun. The R3 wasn't without its own recall issues (bearing on the clutch pull mechanism, and something water pump related).
I wish the MT-03 had been available in the US. When we had the R3 stripped down of all of its plastics, I kinda wanted to ride it around like that.
