Sometimes to go forward, we must go back

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 upto 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 being :-

British

2 Bearing

30mm Axle

No caster/Camber adjustment

No rear ride height adjustment

Following months of testing and regulation writing the class had a test race meeting at Tattershall at the RetroRacer season finale. After all, racing is the best form of testing and we wished to check the rules. A few tweaks after that meeting and the class was finally (re-)born.

For the 2017 season RetroRacer agreed to run the class within their friendly paddock of retro karts dating from the 1960's right up to 1999. A successful first year saw some of the largest grids in the RetroRacer paddock and some very competitive racing with 2018 looking to be even bigger.

The rule book has been developed to try and allow an easy, but fair entry into this sport that we all love. Relative ease of availability of parts and spares. Along with relaxation of certain rules help keep the cost relatively low with people getting on the grid competitively for £500.

For 2019 100UK moved across to the 90's based series F 100UK and as part of the agreement 100UK attended the season finale at Buckmore Park. 

2020 sees 100UK run more independantly and within IKR events across the country to create a fair, fun, cost affective and balanced calendar
