At Bourne Kart Club, we facilitate racing for everybody from 8 to 108 years old. Throughout the course of the year we hold 13 race meetings, 6 on ‘road’ and 7 on the grass circuits.
We cater for both the novice and the experienced racer, with some spending their whole career with us, and some, using it as a stepping stone to go on to bigger things.

So what kart should I have ?  Below is a guide to the karts we race:


Cadets, Junior Cadets

For the ages of 8 to 12 year olds, using the Comer 560 & Comer W60 WPT (60cc sealed ) & Honda GX160 engines.

Junior Honda 160 / Honda Cadet

For the ages of 13 to 16 year olds. A two pedalled chassis, with a Honda GX 160 engine. A cheap, easy to maintain, ‘rev and go’ kart.

Junior Max

For the ages of 11 to 16 year olds, using a Rotax 125cc ‘Junior Max’ engine. The engines in this class must have a log book there seals in tact. Unsealed engines are welcome to race in the Junior Open class.

If you have something different that we do not currently have a designated class for, please get in touch as we also run a Junior Open class which currently features karts such as GX 200’s, Mini Max and TKM’s. Should we start to get larger numbers of these, we will consider running a separate championship for them

The following classes are ‘Senior’ formula with a minimum age of 16 years.

Senior Honda 160cc

This class is a recent addition to the club. It is very similar to the Junior Honda 160cc class, enabling a driver to progress straight from being a Junior to Senior with very little work to do. Also, it is a low cost, easy to maintain, reliable and accessible form of racing for adult beginners too. Please refer to our rule book for engine specifications.


100cc Senior

Our most popular Road class, split in to three groups, one for air cooled engines, one for the slightly faster liquid cooled variants, and also the increasingly popular Formula Blue class. Using a two pedalled chassis, and a direct drive engine.

100cc no3

125cc Gearbox

On a 3 pedalled chassis like a car, using any, mostly motorcyle engines, with gearbox.

Senior Max

Similar to Junior Max, a two pedalled chassis, with a 125cc Rotax engine.

ProKarts 160 & 200cc classes

Minimum age 16, similar to the Junior 160’s, but they use two Honda GX160 or GX200, ‘rev & go’ engines, on a two pedalled chassis. Please refer to our rule book re engine specifications.

175/200 twins ( 4-stroke with gearbox )

These karts sound lovely, not the quickest, but fun to drive. They use a variety of engines, some single cylinder, and some with two, on a three pedalled chassis.

250cc Open Class

This class has been expanded to allow 450cc 4 stroke and Aixro engines. These karts are ‘pocket rockets’, the fastest that we run and not advised for beginners.

Senior Open

In addition to these karts, if you have one that isn’t on this list and you wish to race with us, then please get in touch, and we will try to fit you in. ( We do get some oddball stuff turn up every now and again !)


Grass karts

These are similar to Road karts, but amongst other things, they have the nose cone and body kits removed, 6″ ride-on mower type wheels, a roll over bar on the back bumper, ( to be  2″ above the drivers head ) 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, very cheap to run 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, with the Honda CBR 125 engine, which is a 5 speed, liquid cooled engine.


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.




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 type 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 ( you can use air cooled if you prefer). 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.
