I have one. Its not bad but there are MANY wayyy better bikes out there. When you are doing wheelies its a little hard to find the right "soft spot" for loong wheelies if you don't use the rear brake.
On stoppies its a little to long so on the stock front tire there is not enough grip so it doesn't want to.
If you loose the original exhaust and put a TiForce SUMO its MUCH better.
I would also replace the svingarm with a Hayabusa or a GSXR1000 if you were looking for wheelies and general hooligan fun.
