The ‘250 National’ class is the entry level to 250cc racing…..it’s grunty, it’s fast.

In the main this class shares the same chassis as it’s bigger brother the 250 Inter (250 International). The power plants (engines) are mostly from 250cc 2 stroke Motocross bikes and/or from 450cc 4 stroke Motocross bikes, these engines generally undergo differing levels of modification for their application within Superkart racing that will see these engines happily rev upwards of 10,000 rpm & make in the region of 60 -65HP with a total combined minimum weight of 205kg. They are capable of reaching speeds of 215mph at our faster tracks. Our technical regulations (STR’s) allow for a wide scope of modifications to suit the most of savvy engine tuners.

Some of the key benefits of the 250National class rests in the low  ‘running costs’  & the wide availability of spare parts, couple this with performance & you can quickly see the major benefits come forward for those who desire performance. These Karts are renowned for their reliability & longer periods of servicing engine components such as pistons & cranks.

Some would argue these big single cylinder engines can vibrate your tooth fillings out…….this is in part correct when compared to other engines but it’s a factor that  that quickly dissipates as the fun rolls on & these ‘big thumpers’ deliver the excitement fast, lap after lap.
