dry nitrous kit - starter

Dry Kits - from $490 

These are Basic Stage 1 Quality Dry Kits with All You Need to use Nitrous. HardRider kits are products that have been chosen with experience and are provided with braided lines, premium solenoids and first class fittings and bottles. Basic Kits will NOT become obsolete as you go higher in power and accessories. As you need more, whether its controller or heaters, purge etc we can help you every step of the way.  Another very important point, is while some people that are selling nitrous products have product knowledge, often they they do not have first hand experience installing or using the product. HardRider Motorcycle can assist you with every step, with the right product selection, how to fill and place bottles and solenoids and the nuances that will greatly assist in getting it right the first time. Nitrous fits any and all motorcycles.

With this kit you can add up to 150+hp (with addons and a bigger jet), but we recommend not going beyond 40-60hp if you want to use this kit without the addons and if you stay within the 15-40hp you do not need any addons. This kit uses the air box to spray and AFR is controlled by the EFI sensors.

Comes with everything you need to install and ride. Detailed instructions come with system and we can help you along the way should you hit a road block with video hands on install sessions. Comes with the 1.25LB bottle  standard bottle (but can be changed out for any size bottle and brackets) jets, solenoid, wiring, single or dual snorkel intakes, its all in the kit!  You can ask for no labels on bottles etc.

This kit will work on all our nitrous kits. Motorcycle applications will come with a few different fittings (an 1/8" NPT "T" and 1/8"NPT Coupler) to make it work with most motorcycle nitrous kits.

Spray Bar

Sting the competition with the Black Widow Nitrous Kit. This kit is the most complete kit available. Made for high horsepower 4 cyl bikes, this kit will flow up to 150hp. Finally a complete universal kit made for any fuel injected 4 cyl motorcycle.

Custom fit your spray bar to your preference! Simply install the black widow spray bar, bend your tubing, cut to length and your done.

This kit is the ultimate in tuneablity. Designed for use with or without progressive controllers, this kit jets at the spray bar and at the solenoid for tons of fine tuning ability. Other spray bars do not work with progressive controllers due to poor design. if you mount jets at the spray bar, all the braided line and inside the spray bar acts like a reservoir holding the pressure. It will not pulse the pressure as it would take a second or two to bleed past the jets. By jetting at the solenoid the pressure will build much slower in the lines giving way more control of the nitrous coming out of the hole. Jet changes are now a snap! No more lifting the tank, simply swap the one jet on the solenoid.

Comes complete with a tubing bender, tubing cutter, extra tube, jets, black widow spray bar, braided lines.

Tare function which allows you to zero out the number for the previous weighing objects. Hold function allows you to lock the number after you take the package off the platform.

Nitrous Oxide kits are a blessing. You pay a fraction of what you would pay for big power kits like Supercharger or Turbos and you do not need to have it running all the time, just when you need it. Having said that, there really are pros and cons to each.

Some people think that its hard on the engine and so refrain but the truth is adding a modest power load will have very little impact on your engine. When you go high horsepower you need more sophistication to help your engine dispurse and delivery this power. This comes in timing and mainly AFR (air fuel ratio) adjustments for when you're adding hundreds of horsepower, matching engine work.

But for most riders, an additional 20-80+ horsepower is well within the means of easy peasy. Middle Pic on left basic Dry Kit install. Bottle pic more complex controller install for bigger power. AFR still has to be adjusted, but there are several ways to do this.

For customers around the world, we have made the jump to nitrous an easy one with easy installation instructions and if you need a real person to help with trouble shooting or step by step instruction, HardRider Motorcycle  Installation Support.

The fee for this is $70 per session (max 30 min.). An appointment is required and we are available 9am to 8pm EST. Prepayment is required.
