NitroBoost Nitrous Systems from $490


1: Fits any motorcycle or ATV.
2: Most affordable way to add HP (from $490 basic kit).
3: Very simple to install. For Street or Strip, HardRider has you covered. HardRider's NitroBoost provides "DRY & WET" premium products have been chosen with experience and are provided with braided, copper or galvanized steel lines, premium solenoids and first class fittings and bottles etc.

NitroBoost Kits will NOT become obsolete as you go higher in power and accessories.  HardRider  can assist you with every step, whether its controllers, heaters or bottle fills.

Most riders prefer a smaller bump in power 15-40hp. If you are adding up to 40-60hp, a power commander will suffice to add more fuel with maps you can download (link on our tutorial page), providing correct AFR (air fuel ratio) ensuring your engine is safe from running to lean. Running a small hit of nitrous (15-40hp) to the air box, the air sensors will adjust for the nitrous and add a slight increase in fuel. This is only for dry kits as wet kits are delivering fuel and nitrous together.

Wet kits are generally for carbureted engines, but in some cases needed for EFI engines where there are much, much higher demands for nitrous adding 100+hp. Dry kits rely solely on the motorcycles injectors and the fuel pump to provide more fuel and if either of these are unable to deliver more fuel, then the engine runs lean and ends with severe engine problems. Small nitrous increases no issue, moderate usually requires a stronger fuel pump, adding even more nitrous requires more efficient injectors. Adding a lot of nitrous 100+hp usually will require a wet kit that has its own dedicated fuel pump and solenoid which provides nitrous and fuel together to ensure compatible fuel delivery. Go to our Tutorial Page for more info. Motorcycle nitrous kits.



NitroBoost Basic Dry Kit - Comes with everything you need for a complete installation including a black powder coated 1.25lb. nitrous bottle with high flow valve and burst safety pin, stainless steel solenoid with high power coil use 1/8"npt inlet/outlet ports with .078" orifice,  4 foot 4AN steel braided line from bottle to solenoid, 3 foot steel braided line from solenoid to air box, spray fogging nozzle, all necessary fittings, bottle clamp, 3 jets 15-20-30), wiring and instructions. Optional 2.5lb bottle, larger jets, extra feed line and fittings. Use as is, or add products below as needed.

NitroBoost Custom Wet Kits - Unlike Dry Kits, wet kits require additional fuel delivery, requiring an additional fuel solenoid, plus a fuel pump to provide that fuel. Additionally it requires separate fuel and nitrous lines for each cylinder. Wet kits are used for all carbureted engines and require the wet kit fogger shown below to be tapped into the carbs.  Because wet kits are more complex, they are custom order only.

HardRider provides a choice of two premium aluminum nitrous bottles for your motorcycle, either 2.5lb or 20oz. bottles. This choice comes down to install location and look. Bigger bottles give more longevity and some riders get around this by adding a second bottle in the smaller size. Bottles come with High Flow Valve and Burst Safety Valve. 

The Green Hornet busa below, uses 2-2.5lb. bottles, with premium frame mounts. HardRider also provides 10lb bottles for automobile use or as a mother bottle to fill the smaller bottles.

All HardRider NitroBoost bottles come in powdered coated black with high flow valve and syphon tube (not installed).

NitroBoost solenoids are manufactured using a proprietary plunger material that is swelling resistant. Crafted with a strong stainless steel base, these solenoids are a staple in the high-performance market. The primary purpose of a solenoid is to act as a valve turning the nitrous and fuel on and off. Different sizes of solenoids are available depending on the amount of flow required. Only use a PTFE thread sealant paste to seal fittings.

Copper lines are quickly becoming the go-to choice for nitrous lines. The most obvious advantage of copper lines is that they are much more durable, flexible and stronger. Furthermore, since they are made from a flexible material, they can bend around tight corners with ease. Copper is also more resistant to temperature fluctuations than other metals, allowing it to maintain its performance even in extreme temperatures and it does not absorb as much heat as other materials. More than anything, copper lines are designed to offer maximum efficiency by allowing for greater flow. HardRider provides made to measure custom copper lines with fittings. Copper are custom prepared priced by quotation only.

Motec Dual Lambda

The C125 is a popular model in MoTeCs range of colour Displays and Display Loggers. Striking in design and powerful in functionality, the C125 offers display, data logging, auxiliary control and programmable LEDs all in one compact device. The vivid 125mm screen (approx 5″) is high resolution with up to 32Gig of logging capacity.

MoTec LTC (Lambda to CAN) modules monitor, control and diagnose Bosch LSU 4.9 Lambda sensors, transmitting readings on a CAN bus. When multiple LTCs are used, up to 32 Lambda sensors can be configured on a single CAN bus, allowing a CAN-enabled ECU or logging device to simultaneously monitor numerous Lambda sensors. The LTC is also available as a dual version LTCD to work with two sensors into one module. Send us your requirements by filling out the form in our Purchase/Enquiry section.

If you are running any kind of motorcycle modification like nitrous, turbo, supercharger etc, you are going to require an AFR air/fuel gauge to keep your ratio in the correct zone. This gauge will let you know if for whatever reason your ratio is not  correct and to shut down and re-tune. Problem could be a bad injector, fuel pump or in the case of a nitrous kit, too much nitrous and not enough fuel. With this gauge installed you do not need to worry about damaging your engine.

Heat-Sink Bung Extender (HBX-1) The Bosch LSU4.2 wide-band O2 sensor (shipped as part of the LM-1 kit) is rated to operate at an exhaust gas temperature of < 1300 degrees (F), and a sensor housing temperature of < 900 degrees (measured at the bung) for maximum accuracy and control. When either of these operating temperature ranges is exceeded, the sensor can no longer be accurately controlled. The LM-1 is designed to display an error message under these conditions (currently 08- Sensor Timing Error) rather than provide inaccurate readings. Sensor $149
