Grass karts are similar to Road karts, but amongst other things, they have the nose cone and body kits removed, 5″ ride-on mower type wheels, a 460mm high protective rear bumper fitted and where applicable, the radiators mounted upon it.
(with all the Grass classes, they too can be raced at our Road meetings but it is advisable to alter the gearing and change to Road wheels and tyres when you do this)
70 & 90cc Classes
These are for 8 to 14 year olds. These use a two pedalled kart chassis, with just an accelerator and brake. The engines used are from the Honda C70 & C90 motorcycles, which were popular commuter machines and later often seen as ‘pizza delivery’ bikes. They have a three speed gearbox, with a centrifugal clutch. They are air-cooled, and very cheap and easy to look after.
125cc 4 stroke gearbox – Juniors
This is the next step up from the 70 & 90 classes. Minimum age is 11 years old, providing you have at least 1 years experience in another class, otherwise it is 12 from scratch. The upper age limit is 16 years. These machines use a three pedalled chassis, accelerator, brake and clutch, like a car. Most of our racers use the Honda CBR 125 engine, which is a 5 speed, liquid cooled engine. As things stand, it is probably best to use this engine, as this is the only engine currently eligible for use in this class at the annual British Championships.
125cc 4 stroke gearbox – Seniors
Technically, they are the same as above. The lower age limit is 16 years old. Many drivers who race in the Junior class graduate into this one, and is also a good entry level class for adults too.
125cc 2 stroke gearbox
Minimum age 16 years old. This is a very popular class, again using a three pedalled chassis. Engine choice is open on this one, with many different engines used, from Honda, Suzuki, Kawasaki, Yamaha and others. Most choose to use a liquid cooled engine, although you can have an air cooled if you prefer.
175cc 2 stroke gearbox
Minimum age 16 years old. This was once a very popular class, using a three pedalled chassis. The engine of choice here is the Yamaha 175cc air cooled engine. Whilst the competition is strong, this class has a bit more of a laid back approach to racing.
250cc 2 stroke gearbox
Minimum age 16 years old. This is the daddy of the grass karts. These are not for the faint hearted, nor the inexperienced racer. Some of these karts use engines which are in excess of 70 bhp ! Great to watch, difficult to drive, they are a handful. Not wishing to put anyone off, but it is best that you get some experience in one of the other kart classes first before trying these. Again, a three pedalled chassis is used, and there are many engines to choose from. Most use a motocross from any of the popular manufacturers, Honda, Suzuki, Kawasaki, Yamaha etc.
250cc 4 stroke gearbox
Minimum age 16 years old. This class is growing in popularity all the time. Using a three pedalled chassis, along with a liquid cooled engine. The engines appear to be very reliable and similar to a car to maintain. If you have racing experience from elsewhere, whether it be on a kart, motorcycle or cars, this would be a good place to start.
In addition to a kart, you will also need a good quality Crash Helmet, overalls and gloves. A neck brace and balaclava are optional.
