Welcome to 100UK

100UK is based on the highly successful Formula TKM class of the mid to late 90’s and into early 00’s.

Using Formula TKM chassis up to and including the 1998 Homologation (1998-2000) a harder, longer life tyre similar to the Maxxis SLC of the day. Pre-TKM sequential (or 100UK) chassis are allowed and welcomed providing they meet that original ethos of Formula TKM.

For 2022, we are introducing a 100UK Junior class for drivers aged 11-15. Additionally drivers are strictly limited to TWO SETS OF SLICKs for the whole championship with your first set included in the registration fee.

100UK is visiting 6 tracks across the England and Wales in 2022. The championship is decided on the driver with the most points from their 5 best rounds.


The format will be 3 heats and a final.

Drivers will each get a starting position near the front, the middle and the back which will decide their starting position in the final. Novices will start at the back of each heat.
