HT 190 Air Cooled Bigbore Cylinder Kit

HT 200 Cylinder Kit.

NOTE:  the HT exhausts and cylinders are hand made and are made especially on demand for our customers, Because of the many orders and the growing company these exhausts take about a month after payment to prepare.

This kit comes complete with piston, two piston rings, wristpin, circlips and gaskets (0.25, 0.5, 0.8mm).

When choosing  HT X Tuning  we will get the maximum performance out of your cylinder. 

When choosing  HT X Foot Widening  we will widen the ports 5-6mm increasing the transfer capabilities.  For this option your cases will need to be welded. If the cases are not welded the tuning will not have effect. (Original cases need welding and milling, CNC Cases only need to be milled).

When using an original exhaust such as Sito, Leovince Touring or similar OEM exhaust choose the  original exhaust  option.

When using a racing exhaust such as PM, Malossi, HT, PipeDesign, S&S or similar choose the  Race Exhaust  option.

When using the original OEM 52mm crankshaft size from brands such as Jasil, BGM and Piaggio choose the  52mm crankshaft  option.

When using a 55mm crankshaft from brands such as Jasil, BGM, PM and HT choose the  55mm crankshaft  option.
