172cc aluminium high performance cylinder kit with molybdenum disulphide coated twin ring piston, tapered gudgeon pin, dowelled PM998 high compression billet aluminium cylinder head and gasket set with 3 thicknesses of base gasket. The original concept of the PM Pro-Street kit was to offer the best currently available performance as a bolt on kit using the latest high quality materials and technologies to give a genuine 25 HP (rear wheel) along with good long term reliability for fast every day road going use.

One of the key features of the kit is having generous amounts of alloy material in the right areas for owners/ tuners wishing to push the HP limit upwards without suffering the usual problem of breaking through into water galleries and fresh air when porting to the extreme.
