Wizards of NOS - Pro-Series 250 - Wet Motorcycle Nitrous Kit


The unique concept behind the Pro-Series 250 is the most powerful yet most effective direct port single solenoid system on the market and is specifically designed for 4 cly motorcycles which are looking for bigger power increases. Tests have proven that in the vast majority of cases (when adding up to 250bhp) a Pro-Series 250 can out perform any other direct port kit, whilst being more user friendly.

No other system has such a desirable combination of low price, ease of fitting, user friendliness and superior performance. 

WON designers put great thought in to ease of fitting, performance and cost when developing this unique system (or concept), to make sure it ticks all the right boxes, for you and your bike. If you want up to 250 extra bhp, why search further, only to find a more difficult to fit, more expensive and less effective system, when you’ve already found the best?
