performance parts:

parts to improve or change the performance of your scooter

This does not necessarily mean giving your scooter higher top speed. Remember in New Zealand your 50cc scooter is only legally allowed to be capable of 50km/h. However you can change parts so that the scooter still does 50km/h up hills, or with a trunk full of bricks, or into a headwind. Replacing parts on your scooter to increase the torque output is certainly beneficial as it will help you maintain speed, and get off the line at traffic lights a little quicker. Torque is what accelerates your weight against anything trying to resist it, including gravity and inertia. Modification or replacement of parts may mean that your scooter runs more efficiently or accelerates better to get you clear of traffic.

about scooter engines - overview

The majority of 50cc scooters and many bigger scooters have 2-stroke (also "2-cycle") engines. These have higher output than 4-stroke / 4-cycle engines (as found in most cars) however they are difficult to keep running as efficiently. When it is a 50cc scooter efficiency is still much higher if you consider that an engine around 40 times smaller than a car's is moving one person around. The parts are made of materials similar to other motorcycle/car engines, and a typical Japanese 2-stroke 50cc will rev to 6.000rpm under normal use. The main parts and systems are similar, they need air cleaners, a device for mixing air and fuel, the combustion engine itself, and an exhaust and muffling system.

tuning to factory settings:

returning your scooter to the factory OEM recommended settings

This could be called a "tune-up". Your scooter was designed to run with certain restrictions in the intake and exhaust and carbon or unburnt oil deposits in exhausts, and clogged air cleaners can reduce the efficiency and power of your scooter.

Other parts wear out and again reduce performance. Most modern clutchless scooters use a belt-based CVT style transmission. These belts and the weight rollers in the variator pulley wear out naturally and slowly reduce the distance that they extend the belt to on the driving pulley. This means that the same top speed can not be achieved.

If your scooter is going slower now than when you bought it, or slower than others of the same model (and you are not heavier) it is probably a combination of worn drive parts and need of a tune up. Scootling stocks replacement drive parts for the majority of 50cc scooter models so if your scooter needs to regain some life please contact us.

Driveline parts

Other parts wear out and again reduce performance. Most modern clutchless scooters use a belt-based CVT style transmission. These belts and the weight rollers in the variator pulleys wear out naturally and slowly reduce the distance that they extend the belt to on the driving pulley. This means that the same top speed can not be achieved. Worn belts also tend to slip under load, so your scooter may accelerate from a standstill slower if its belt is worn. Sometimes this is given away by a slipping sound and intermittent acceleration coinciding with the engine RPM increasing without the bike accelerating any faster.
