Bemsee continues with what was an experimental addition to MRO 600 in 2022 with the formal launch of the Moto EVO and Street EVO Series for 2023.

This will still run within the MRO 600 grid but will be its own Championship.

All machines competing in the 2023 Moto EVO & Street EVO Series class must comply with the regulations on the TSM Website. The regulations are additional to the ACU Standing Regulations as laid out in the ACU Handbook.

For the 675: The series is open to riders with a minimum age of 16 who possess a valid National ACU or SACU license, or a Novice - Clubman license if over 17.

For the 765: The series is open to riders with a minimum age of 17 who possess a valid National ACU or SACU license, or a Novice - Clubman license if over 18.


The ethos of the series. 

Here at TSM we believe that the ongoing cost of tuning and refreshing engines is getting too costly, we also believe and have proven in GP2, that a relatively stock engine can be used to produce similar lap times if the chassis is tuned instead. The GP2 EVO and Street EVO series is all about exploring that option with a direct view on preparing riders and bikes for GP2 & GP2 EVO at BSB. 

Until now the kind of geometry parts required to tune a chassis have not been permissible in UK racing, primarily due to being bound by the words ‘homologated manufactures part’, however due to Bemsee’s foresight and our development, we have now changed that and can present a new way of going racing. I sincerely hope you will enjoy the benefits of EVO racing and help us show the world how it’s done.

Whilst an EVO bike must consist of a stock chassis and swing-arm, it is allowed to use a custom rear suspension linkage that is both adjustable and far better for the purposes racing, the series also uses adjustable offset yokes, rake angle adjusters and swing-arm offsets.  These items open a new world of motorcycle set-up, one that uses chassis programs to give you detailed information on your bike’s geometry configuration, but it does require a good understanding of geometry to operate effectively.  So, to assist we will have a chassis and suspension engineer on hand at every round to help you learn and understand this, we are going to give you the knowledge to take control of your suspension and geometry set-up by taking your knowledge and your ability to make the right changes to a whole new level, a must for those with aspirations of making a career out of racing.  For everyone else, we will introduce you to a new level of motorcycle handling and a great understanding of why! 

As the series develops, we will look at the regulations frequently and adjust accordingly.
