StreetBike 50-4 Air box Nitrous System, to suit 4 cylinder motorcycles:

Wizards of NOS StreetBike 50-4 Air box Nitrous System to suit 4 cyl motorcycles.

The unique concept behind the StreetBike 50 makes it the simplest yet most effective system on the market as it’s specifically designed for motorcycles which have retained their original air box. The distinctive feature of the StreetBike 50 is it’s single nitrous injector, which when mounted in the air box dilutes the initial flow of nitrous to the engine to produce a smoother transition in power delivery, than any other system. Independent tests have proven that when adding up to 50bhp, a StreetBike 50 will outperform any other direct port kit, whilst being far more user friendly.  

No other system has such a desirable combination of low price, ease of fitting, user friendliness and superior performance. Despite the low price, this system still benefits from the same list of unique ultra high quality components as our Pro-Series systems. The StreetBike 50 has been designed to fit a stock street bike without any major modifications and as a result can often be fitted without removing more than the fuel tank, in less than half the time of other kits. 

The WON team have put a great deal of thought into the ease of fitting, performance and cost when developing this unique system, to make sure it ticks all the right boxes, for you and your bike. If your bike still has an air box and you want up to 50 extra hp, why search further, only to find a more difficult to fit, more expensive and less effective system, when you’ve already found the best in all respects?

All Kawasaki inline-4 / 4 cylinder engines
