TUNING ROAD – for everyday use

For race use only. Not admitted in the area of the German StVZO! Product description
Need more power, but want to keep your feet on the ground
Then reach out for the 85 – 115 ccm class. A longer transmission, a 19er carburetor and a tuning exhaust system will be necessary. Add a 4er disc clutch to that. Ranges up to 10 horsepower, speeds to 95 km/h and heftier acceleration are yours. Our tip: the MALOSSI 112 ccm direct induction! Technical data 50438411:117
