motorcross exhaust on sv

anyone fitted one or knows what its like??? i like the shape of them, and just wondering whether its advisable or not. is there too much restriciton in the size of the ports or should it be fine??

If the inlet and outlet diameter is the same size as the SV link pipe then you should be ok.

I take it that M4 exhaust cost a bit then?

havent found out the price, but seen a couple of cheap off road cans which would look good shortened. they are a smaller diameter too which i prefer than the bulkier sportsbike ones

the link pipe on a crosser would be smaller

Usually a stinkers can is quite small, you need what's called a stinger on the end of the expansion chamber to cause the resonance, that's effectively the link pipe and the diameter is tiny. Not suited to a 4 strokes gas flow at all.

Bear in mind that a 2" I/d can, can restrict flow on a tuned engine, some big twins run twin 60mm I/d pipes. Looking at the road, untuned cagiva in the garage the "linkpipe" is about 20mm wide. It may be a little strangled!

2" is good for the SV650.

Yup the 60mm ones tend to be on thous. Anyway you'll struggle to get anything to run sweet with a silencer from a crosser.

Aha, work good on single silencer bike twins.

I think tygaboy has done an off-road ish SV, it looked very sweet, the "tank" was just an airbox cover and the fuel went under the seat.
