TUNING RACE – for professionals

For race use only. Not admitted in the area of the German StVZO! Product description
Italian racing champion STEFANO SCAURI has joined with a noble Italian manufacturer to create high quality aluminum cylinder kits that carry the proud name “SP09, Parmakit by Scauri”. SP stands for Sport Production, a fitting name that shines with generous transfers, a one piece boost port and a VERTEX piston with an 1.00 mm piston ring. Available in two cylinder versions, with and without divided exhaust. Timing on both kits is identical. Cylinder version 1 is built without an exhaust bar: 38 mm,~ 67% exhaust width. Ideal for tuning novices and touring fans. Cylinder version 2, with a divided exhaust and 46.5 mm ~ 82% exhaust width, is designed for sport and racing usage. The motor casing will need modification, but in the first step will not need welding. The pinch gap should be at least 1.3 mm and can be adjusted exactly through the base gasket included in delivery. Exhaust stud distance is 62 mm, exhaust systems will need modification, or rather, outfitted with a modified flange disk. The SP09 Evo has a forged piston and a modular cylinder head. Available with 58mm and 60mm bore (105mm con-rod crankshaft necessary).
Conclusion:
depending on degree of modification and cylinder version, the motor is extremely versatile, from thoroughly dependable daily commuting to pure sport pleasure.
