The 1970s and early ’80s was an exciting time for motorcycle Grand Prix – probably the last time privateers had a genuine chance of mixing it with works bikes. GP Originals has presented the sights, sounds and smells of this Post Classic racing era since 2017.

From 2017-2024 GP Originals was the go-to Series for post-classic racing motorcycles such as the ubiquitous Yamaha TZ250 and TZ350. This period also championed Rotax engines and a wealth of frame-makers including Maxton and Harris. These ‘Original’ racing motorcycles represent the first instances from which copies or reproductions could be made. Naturally, we always included the customer and replica machines which embraced the concept of our Series. The word ‘Original’ also means individual, free-spirited – we all like the sound of that.

Two-stroke, post-classic racing

2024 was challenging year for motorcycle racing across both short circuits and real road racing. After much consideration it has been decided that GP Originals has reached its peak and is now at the point where it would require considerable compromise to continue. NG Road Racing has forged a new space for your GP post-classic, two-stroke machines and are running the new ACU National Championship. NG is the UK’s established home of two-stroke racing and they understand our needs perfectly. This opportunity is there for all levels of rider – we cannot emphasise enough that all post-classic, two-stroke riders need to pull together to ensure a competitive and ideally dedicated space to race these special machines. NG will provide a dedicated grid where 20+ are entered, please support them.

Eligibility questions

GP Originals have been the only dedicated post classic 250 and 350 two-stroke GP series available since we began in 2017. Love them or loathe them, our rules kept the racing competitive and the bikes ‘in period’. We kept a keen ear on what our riders were looking for as we had a clear message that our kind of people wanted tighter period style machines. All our riders were racing on the same type of machine and the same style of treaded tyres, no wets, no warmers.
