Dasa 850SS Top End Kit

Dasa has done it again. Now able to pull a staggering 865cc’s from a standard crank shaft this is a potent engine package for any rider. First we started with our monster 5 port sleeves pressing them into our billet cylinder “available in many colors” and perfecting the port height for ultimate bottom end. We then put the strongest/lightest 89mm pistons we could find from Wiseco making this a arm yanking 865cc animal. If that was not enough we added our low profile power valves to increase performance through out the rpm range. To install this cylinder kit you will need to epoxy then fly cut the crank cases to accept the larger sleeves. If you’re unable to do the machine work or find some one up to the job simply send us your crank cases and we will do the job right the first time!

Ported Billet Cylinder

Wiseco 89mm Pistons
