On my own I would like to add that customizing finds a place in stunt riding with full dedication, as well as in other classic forms familiar to the eye of the layman. While creating their own bike for the soul, people look for self-expression in technology, and the stunt rider modifies the finished bike to express itself in the dynamics of tricks, skill and experience. Every motorcycle built for performance is as unique as its owner.
In the previous article, we talked about the modifications to stunt riding bikes that a beginner needs. From the moment when the pilot is more confident in wheelie and goes into stoppies, it becomes necessary to solve technical problems that arise when performing tricks in their long performance.
What problems arise at a more advanced stage?
- Engine oil starvation
- The engine overheats due to poor wind blowing
- Many tricks require a rear brake, but how do you use it during a trick?
- How to ride a motorcycle during a tricky stunt?
Perhaps the most dreary part of the motorcycle rework. When your skill level has increased so that you are able to hold the motorcycle upright for a long time, the problem of oil starvation will become especially acute. In addition, in parallel with this, there are difficulties with ventilation of crankcase gases.
Depending on the model of the motorcycle and the level of the pilot’s capabilities, everyone solves this problem independently. Someone needs the installation of an oil trap, someone alters the partitions in the crankcase, and for some it is enough to fill in more oil to calm down.
It is recommended to fill in oil at the top risk when the motorcycle is level, without a tilt, ideally on the trolleys or the center stand.
In any case, before addressing engine starvation problems, you should examine your motorcycle’s oil system. It is difficult to talk about a universal method, because there are many special cases.
Forced engine cooling
Stunt riders usually ride on special sites and, as a rule, these are not particularly high speeds in a short period of time. This means that the motorcycle engine will not cool down at a decent level, it will start to overheat, like your nerves after the thirtieth attempt to learn a trick.
A forced cooling system is required.
In addition to temperature sensors, a fan switch, some put an additional fan, and someone finds a more powerful radiator, cheats with a thermostat. It makes sense to think about whether it is possible to increase the channels through which the system is cooled?
Innovations should be based on the structure of the motorcycle model, it is foolish to change something if you do not know how the whole system works.
When a pilot performs a trick while sitting on the steering wheel, happily swinging his legs, how can he reach the rear brake? Stunt rider, of course, is a superman at five minutes, but not a Fantastic Four hero and cannot, like Mister Fantastic, stretch his body to squeeze out the rear brake with his foot while sitting on the steering wheel. We have to install a backup brake. If you take a closer look at stunt riding motorcycles, you will notice another one near the clutch lever – the rear brake. By the way, we often see an additional caliper on the rear brakes. Typically, this system works according to the principle: the foot lever operates one support, and the manual lever operates both.
In addition to calipers, pilots can use wider brake discs.
Replacing sprockets and chains
The chain can be replaced with a reinforced one, by the time the rider’s skill level increases, the time for replacing consumables is just right. The chain could also be on this list.
The stars are changed with the expectation of playing with gear ratios in order to control the characteristics in search of the right combination.
Shortening the exhaust system
We discussed the exhaust system in the articles:
“The exhaust system of a motorcycle – what is its main task?”
“Exhaust system design, what is it useful for a pilot to know?”
The exhaust pipe, due to its length, interferes with many tricks. Exhaust gases and burns on the pipe, if it is in the stock state, greatly irritate the pilot. And yes, when it falls, it is also scratched, damaged, crumpled … Why then leave it? Stunt riders shorten the exhaust system in every possible way or change the “can” to make it easier to perform.
Tank shape and seat opening
By the way, about convenience. Whenever one of the city racers tries to repeat the acrobatic stunt stunt on an unprepared motorcycle, it rarely ends with success. Because the professionals are cunning even here! The pilot’s tank lid is concave in such a way that there is a platform to sit or stand on the tank. In stock form, such somersaults on the tank cannot be done right away, the rounded shape is not an assistant to that. On the tanks of professionals, we see a curb along the edge, which prevents the pilot from falling.
The hole in the seat under the foot is not made by every rider, but it makes it much easier to perform stunts.
It would be nice to stick an additional textured pad on the surface of the tank and seat to increase the grip of the rider’s body with the motorcycle.
Additional little things
Not so much a necessity as a convenience:
- You can rotate the emergency engine stop button away from you to avoid accidentally pressing it during a trick.
- Many pilots are tweaking the idle system to make it easier to perform.
- All protruding wires and cables should ideally be secured with clamps so as not to snag.
- The levers themselves are looking for the easiest to use and sometimes shorter ones.
Stunt riding is an art like other sports. Therefore, you can constantly improve your motorcycle and improve your skills.
