Wizards of NOS - StreetBike150BHP-4DRY Motorcycle Nitrous Kit

The StreetBike150BHP-4DRY is a simple to fit four injector dry nitrous system, which is the most effective on the market.  This system is designed and manufactured by WON to the highest possible standards, specifically for four cylinder fuel injected motorcycles/bikes. The distinctive feature of the StreetBike150BHP-4DRY is its four nitrous injectors, which when appropriately mounted in each intake trumpet, reduces the effects of reversion.

Independent tests have proven that a StreetBike150BHP-4DRY outperforms any other brand of like for like nitrous kit, whilst being more user friendly and easier to install. No other system has such a desirable combination of low price, ease of fitting, user friendliness and superior performance.  Despite its low price, the StreetBike150BHP-4DRY still benefits from the same list of unique high standard features as our Pro-Series systems, so you can rest assured that the nitrous side is well taken care of.  WON designers have put a great deal of thought in to the ease of fitting and performance when developing this unique concept, to make sure it ticks all the right boxes, for you and your bike.

Most fuel injected bikes have adequate surplus fuel capacity to match a nitrous delivery of up to 75 HP when using the standard fuel system.  Being a dry nitrous system, it is the customer’s responsibility to ensure adequate fuel is added to avoid a lean mixture.  There are a number of options to increase the fuel flow, but the method recommended by WON is to have a 2nd switchable fuel map (to suit the nitrous being added at any time) programmed into the ECU.  Should you choose a different option and add a tuning box to deliver the maximum fuel flow possible, you can keep adding nitrous until you reach a level that suits you.

With a wide range of jet sizes available (from 5bhp up to 150bhp), the StreetBike150BHP-4DRY has the ability to deliver, as little or as much power as you’ll ever need, within that range.  

Please note that in order to deliver the maximum potential from a StreetBike150BHP-4DRY system, you may need to carry out certain other modifications to upgrade your fuel injection system.  

If you want a quick and easy boost in performance of up to 150 HP extra, but don’t want to sacrifice reliability and peace of mind, this is the system for you.
