MVT S-RACE SP1 exhaust for MBK 51 / AV10 / AV7 round or square swingarm

Approved to CE standards

Stamped/welded/varnished half-shell type exhaust. This MVT S-RACE SP1 exhaust is a exhaust designed for engines with diagrams oriented at low revs, it will give its full potential between 6,500 and 9,000 revolutions. It therefore works perfectly on a completely original engine to free it up well and even on small 70cc with low diagrams like a MOTOBECANE AV7 engine with a small 70cc AIRSAL ! It can also produce great performances on an unprepared POLINI W 70 cylinder! In combination with an original engine or a cylinder with diagrams of 115° / 165° at most with a fairly low compression ratio, it will be very comfortable. It comes with all the necessary mounting materials including the mounting kit for round swingarm and rectangle arm.
