Supercharger kit for 49cc, 50cc-125cc motorcycle, scooter, dirt, pit and pocket bike

Keener, Северная Каролина, Соединённые Штаты Америки

Superchargers and Do-It-Yourself Bolt-on kits that provides 50cc motorcycles with twice the acceleration compared to non supercharged motorcycles

Project pitch

Our team has developed a compact and powerful mechanical device for motorcycles, motorbikes, scooters, mopeds, mofa, pit bikes, dirt bikes and pocket bikes. The device, based on a belt-driven air compressor (supercharger), improves the performance of most common 50cc four-stroke single-cylinder engine. Having a bolt-on design, the supercharger kit increases an engine's acceleration capabilities. Thus, a motorbike can reach its maximum speed in half the time required before the supercharger was installed.

Our innovations

  1. We have created a supercharging system consisting of an air compressor, boost storage tank and gas exchange unit, that provides steady functioning induction to a small engine in any operation mode.
  2. Our efficient mechanical control unit has no electronics, so its production is inexpensive.
  3. Also, our machine is suitable to supercharge any two-wheeled machine powered by a 4-stroke 50cc engine.
  4. Now an owner of the legendary Honda Monkey can, my themselves, mount and dismount our Do-It-Yourself (DIY) bolt-on supercharger kit within one to two hours. This is the first ever kit that does not require any additional tuning after its installation completion - just mount and drive.

Supercharger design ready for mass production

Compressor: Vane-type Weight: 2.9kg
Working rpm range: 500 … 10,000
Max rpm (cont): __10,000 Max rpm (inst): _12,500 rpm (within 60 seconds)
Max boost pressure: 1.2Bar (17.5 PSI)

Acceleration capabilities of motorbikes with and without supercharger

Stock vs supercharged acceleration diagram.

As can be seen from the diagram, the supercharged motorbike has an acceleration time of 8.5 seconds to reach a speed of 50 kilometers per hour. The stock model reaches the same speed in 14.5 seconds. Thus the time to reach maximum allowed speed for supercharged motorbike is less than that of the naturally aspirated stock motorbike by 40%. The technical specification allows 50 kilometres per hour as the maximum speed for the target bike.

Approval from Global Automotive Engineering Community

A reliable way to supercharge small engines was presented in our paper at a Society of Automotive Engineers (SAE) conference.


High Performance Characteristics of a Motorcycle Powered by a Small Four-Stroke 50cc-125cc Engine at the Expense of a Positive Displacement Air Compressor as a Supercharger

The paper and presentation were appreciated very much by the conference participants and specifically by executives of numerous motorcycle OEMs including representatives of the Big Motorcycle Four.

Having created a well levelled supercharger, we also tried many versions of supercharger installation on the target motorcycle, and the best way is based on using DIY fundamentals. Now any motorcycle operator who handles a simple screwdriver can mount the supercharger kit. Not a single part of the target motorcycle or its engine is needed to be modified at all. When desired, the supercharger kit can be dismounted and the motorcycle restored to its original appearance
