Motorcycle Nitrous Oxide - SB150Bi Kit

StreetBlaster 150Bi

StreetBlaster 150Bi

Multi Injector Nitrous System for Fuel Injected Bikes

The Street-Blaster 150Bi is the highest capability injected bike system in our “off the shelf” range and offers the ultimate in direct port technology, delivering outstandingly even distribution. This system is specifically designed for the serious Drag racer who wants to maximise his performance and results. Like our lower power rated Street-Blaster 75 system, the Street-Blaster 150Bi is supplied with 4 individual nitrous Venom injectors and 4 individual fuel Venom injectors (which can usually be fitted in to the intake trumpets) but unlike the Street-Blaster 75, this system utilises our unique Axial Discharge Y-Blocks, to achieve perfectly even distribution to all 4 cylinders. The Street-Blaster 150Bi comes as standard with a 1Kg bottle, which has the advantage of being able to maintain a more constant bottle pressure, than the 20oz bottle which comes as standard with the Street-Blaster 75. Independent tests have proved that a Street-Blaster 150Bi will produce quicker ET’s than any other direct port kit. If you want the quickest ET’s from your bike, why search further, only to find a more difficult to fit, more expensive and less effective system, when you’ve already found the best?

WON designers put great thought into the ease of fitting, performance and cost when developing the Street-Blaster 150Bi, to make sure it ticks all the right boxes for you and your bike. If you need a nitrous system that can deliver as much torque/power as you and your bike can handle, with unrivalled reliability to give you total peace of mind, then you need the Street-Blaster 150Bi, so order now!
