Wizards of NOS - Pro-Series BD4-250 - Dry Motorcycle Nitrous Kit
The Pro-Series BD4-250 is a ‘dry’ nitrous system that is manufactured to the highest possible standards and designed specifically for 4 cylinder, fuel injected competition bikes. The unique concept behind the Pro Series BD4-250 makes it the most advanced and most effective direct port dry system on the market, capable of increasing engine power by up to 250 HP.
The distinctive features of the Pro-Series BD4-250 are;
1) Its unique use of Y-Blocks rather than a rail or shower heads to achieve perfect distribution.
2) Its unique nitrous Discharge Tubes, which eliminate the drawbacks of nozzles and when mounted correctly act as air amplifiers and increase the airflow into the engine along with the nitrous.
The Pro-Series BD4-250 offers;
1) Superior performance at a very competitive price
2) Peace of mind due to reliably and effectively delivering the exact volume of nitrous oxide required, when required.
No other system offers such a desirable combination of ease of fitting, advanced technology and superior performance. This system benefits from all the unique and high quality features expected of a high end WON nitrous system.
Independent tests have proven that our Pro Series BD4-250 will outperform any other direct port kit on the market bar none, whilst being more engine friendly.
The WON design team put a great deal of thought into creating the Pro Series BD4-250 system, to ensure it delivers the best for you and your bike. If want up to 250 extra HP and the most advanced injection design available, why search further, only to find a more difficult to fit and less effective system, when you’ve already found the best?
