Restricting the SV650(25KW) with full Akrapovic

[DimmniBurek]

Hi, I will probably buy a SV650, but the thing is I must restrict it on 25KW, because of our law...
No matter...
There are two ways to restrict the bike
1.-A plate with smaller diameter beetween the exhaust and the cylinder
2. Physical restriction in the carb(you can not open the gas pulley fully)

The thing where the problem comes out is that the bike has a full Akrapovic exhaust sistem. Will there be problems with maybe a 1KW more power?

I shouldn't see there being a problem, but why get a bike that has a mod to increase power, if you need to lessen it? Sounds to me like you need to find a standard bike to restrict, not one that has had work done to improve power. The full Aky system is supposed to increase the SV power by about 4bhp - 2Kw, although to get this I would think it also need to be jetted/mapped correctly. Restricting it now might mean the work needs to be undone.

Hi

In theory the plate after the carb should restrict it by not allowing enough air in to provide more than 25kW. In practice not sure that this will be 100% correct.

However I agree with Fuzz on finding a non played with bike. Fair chance that the Akrapovic system will be biased towards top end power at the expense of low down power. With the restrictor you will still loose the low down power but not have any gain in top end to go with it.

All the best

The bike is Streetfighter and I might buy it, I will wait 2 years and then derestrict it...
