Simple Madass : My home made 39t gear installed

16:39, this will make my madass reach 112kmh top speed, but i don't test it yet how big the loss of torque will be. I ride most of the time in the range of 60-80kmh, with stock 16:46 gear, engine shakes significantly when i reach 80kmh at 4th gear, that's pretty much uncomfort to my hand and my butt, event for 15minutes reading
With this new combination, i hope it helps reduce the engine shakes. If torque loss is too much, i will need to look for front 15t sprocket to be 15:39 combination, max speed will be around 105kmh, somewhere in between 16:46 and 16:39 combination.

Gear taken from Ninja 150R, TK Racing 428 39t with 6spokes, cut the spokes, drill the holes, few hours with metal saw and drill station. Combine with 108link 428 chain and i am ready to go.
