I built this for fun for my 17 year old son and spent a few more dollars to get all the upgraded parts for the motor, along with finding the perfect bike to do speeds, faster than others, you see on the road, and I succeeded, this thing is a blast and even painted it and added the decals to match my 200mph bike, I love speed, and if you do too, than this will be perfect, now that my son has a license it's just sitting in the house, this motor is literally brand new and has not even been finished with the break in period, it says you need to drive through 5 full tanks and he has only done 2, so its gonna be even more faster once complete, the price is firm and no I'm not looking for trades, thank you
