Why convert to 520 chain and sprockets?
Depending on the bike and what size you are converting from you can gain 4-8
hp just by putting a good quality 520 chain and lighter sprockets on the bike.
The lighter chain and sprockets create less centrifugal force which lets the
motor spin them easier. For stunting, the smaller pitch causes less drag. Most
good 520 chains are rated to 750cc but there are ones rated to 1000cc also.
What’s the difference between 520, 525 and 530?
Pitch can be characterized by the thickness and weight of a chain. The first
digit (5) indicates the center-to-center distance between chain pins. The second
and third digits (20, 25, 30) indicate the chain’s width, measured between
the inboard surfaces of the inner sideplates.
Because wider chains are typically stronger, the second and third digits also
indicate a chain’s strength. Higher numbers correspond to greater strength,
i.e. a 525 chain is stronger than a 520. This additional strength is achieved
through increased roller diameter, pin diameter, pin length and plate thickness.
Will take the most weight off of your bike and will increase horsepower, however
it is important to note that by decreasing pitch, you can expect faster wear
especially on bigger bikes because the drive forces are getting spread over
a slightly smaller surface area.
Middle of the road, standard chain that comes standard on most 600 and 750cc
models. 525 is more durable, but heavier than a 520 conversion.
The heaviest, thickest and most durable chain pitch. Comes OEM on most 900-
Don’t Forget! A worn or poorly maintained chain will wear an aluminum
If you can't find your bike model under the pitch you are looking for, chances are the manufacturer does not offer that pitch for your model. Please check out the other pitch options or email for assistance.

Rear Hand Brakes
Rear Hand Brake Kits - After your bike is equipped with the basic safety equipment and sprockets, a handbrake kit is the next vital piece.
A handbrake came onto the stunting scene much later and in actuality within recent years gained popularity.
With the sport pushing its bounds into new territory came tricks that involved the rider in a position in which he cannot access the rear brake to control the
balance point of the motorcycle.
When tricks such as seat standers, highchairs, and spreaders came on the scene at first it was not necessary to use a handbrake,
however these tricks quickly developed into scraping while in a highchair or spreader which involved the use of a hand mounted rear brake.
Single Caliper Hand Brake Kits vs Dual Caliper Hand Brake Kits - Always a good debate and once again no right or wrong answer. For a starter, we always recommend our attractively priced Best Selling Junction Valve Kit.
We have sold thousands upon thousands to our customers and riders over the years and they love them!
The kit simply consists of a new Brembo Master Cylinder, an HEL Stainless Brake Line, and our Dual Fitting for your specific model.
This kit will allow you to gain control of the rear brake with a left handed lever, while maintaining all the function of your foot pedal and rear caliper.
The optional ALL NEW Shorty Clutch Cap & Lever (Dominator Clutch) installs on the top of the Hand Brake master cylinder and eliminates the stock, clutch perch and lever.
This brings your levers closer together and allows for greater adjustability. The added features of the new Dominator clutch cap are:
True Easy-pull Feel, Stronger more ergonomic lever, position adjustment on clutch lever, and choice of color.
For the advanced stunters who feel they are ready for more braking power, our Dual Caliper Kits fit the need.
A few good reasons why to buy a dual set-up bracket:
1. If you damage your hand master cylinder you still have got your foot brake.
2. If you break off your right foot bracket you still have your hand brake.
3. How often will you have a spare hand master cylinder with you?
4. Rear master cylinder adapter style hand brake set-ups aren't back up proof. If you mess up your hand master cylinder and air gets into your line you are left without rear brakes. This will not be the case when you are operating with a dual set-up bracket.
5. For competition riders two brake systems are better than one. Even professional riders occasionally break parts. In competition the judges aren't going to give you time to fix a brake problem, but if you're running a dual caliper set-up, then you have nothing to worry about.
SubFrame Cages / Stunt Pegs
SubFrame Cages/Stunt Pegs - The last piece of our basics to stunting is the subcage. Subcages are very similar to crash cages but for protection of a different sort.
While crash cages are protection for the frame itself and motor mounts, subcages focus on protecting the subframe of the motorcycle.
Certain subcage applications will also eliminate the stock passenger pegs and relocate them to a different spot which is more becoming for staggered stance wheelies among other tricks.
These pegs will in some cases be solid mounted to eliminate the possibility of them folding up on the rider when doing wheelies on the passenger pegs.
Stunt Stay Bar
Stunt Stay - Meant to replace the upper stay on the motorcycle which usually holds the upper fairing and gauges in place.
This is only necessary when running a full fairing bike and is meant in like fashion as both the subcage and crash cage to protect the front of the bike and provide
increased stability for the front end of the motorcycle.
This will not save the front fairing from damage. Please view our selection from Racing 905 Here!
Basic Wheelie - Lifting the front of the motorcycle off the ground by means of either power or use of clutching the bike into a wheelie. There are many variations of the basic wheelie, some of which wil be listed below.
Circle A wheelie performed traveling entirely within a circle. "The Circle wheelie is the epitome of control on a motorcycle" -Matt Gorka (can also be combined with all other wheelie variations).
12 O'clock Very high wheelie, past the normal balance point of the motorcycle.
High Chair Wheelie with the rider's legs over the handlebars.
Tank Wheelie Wheelie with the rider sitting on the tank with legs spread.
Coaster A wheelie that is balanced without the acting force of the motor i.e. with the clutch pulled in. The Wheelie is so far back beyond the balance point of the wheelie that the rider must constantly ride the rear brake to keep the wheelie from falling over backwards, effectively slowing down. A rider can pull in the clutch to create the effect of a wheelie with no engine noise. Conversely some riders will pull in the clutch and peg the engine on its rev-limiter, called a "rev-limiter coaster"
Frog Wheelie standing on tank during wheelie
Seat Stander Wheelie standing on the seat of the motorcycle.
Ralph Loui Circle Wheelie with the rider's Right foot on Left Peg.
Watch Tower Standing on the windshield riding with the bike at 12'oclock.
Man-dom Riding Wheelies with two men, possibly more.
Ape Hanger Hanging from the bars with one's hands while doing a 12 O'clock, scraping the bike's 12 o'clock bar and allowing the riders feet to drag behind the bike.
Cliff Hanger Hanging from the bars with one's feet while doing a 12 O'clock.
Stoppie Lifting the rear wheel of the motorcycle using momentum and braking force. Also referred to as an Endo.
Biscuit Eater Stoppie with the rider's legs over the handlebars. Also known as the "highchair endo"
Burnout Using the power of the engine and braking force to cause the rear wheel to spin, heating the rear tire and producing smoke.
Suicide Burnout Burnout with the rider dismounted and standing in front of the motorcycle.
Chainsaw An extreme form of Burnout performed by the stunter standing beside a motorcycle laying on its side holding the motorcycle exclusively by the right handle bar. Then causing the bike to "orbit" around the rider while maintaining control during the burnout.
Merry -Go-Round Rider lays the bike on its side and climbs onto it. The rider then leans back on the bike while holding the throttle, causing the bike to spin round while doing a burnout.
Acrobatics - Kneeling On The Right Side Of The Bike, With The Bike Laying On The Ground And Feathering The Gas And Spinning Around On The Ground
Switchback Any stunt performed with the body facing the rear of the motorcycle, opposite the direction of travel.
Christ A stunt performed with the rider standing straight up on the seat or tank of the motorcycle with both arms extended while the bike is in motion. Also called a "Jesus Christ" or a "Cross". Can be combined with a switchback.
De activator Riding a wheelie on idle and jumping off the back of the motorcycle.
