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 presents the sights, sounds and smells of this Post Classic racing era.

The Series highlights 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 include customer and replica machines that embrace the concept of our Series. The word ‘Original’ also means individual, free-spirited – we all like the sound of that.

Round Four is back on at Donington Park

Following the huge disappointment of being cancelled from our Brands Hatch GP event, Thundersport GB has stepped up to replace the round with four points-scoring races of 10 laps plus timed qualifying and a Sunday warm-up. As per our usual format, this is a dedicated grid of our post-classic, two-stroke 250 and 350cc machines only. No road bikes, modern bikes or four-strokes to mix up your race. We are pretty much guaranteed to receive every lap paid for under the super-efficient organisation at TSGB.

Enter today and be part of the best post-classic series around. As always, your support is essential and much appreciated by the riders and wider GP Originals team.

Eligibility questions

We are the only dedicated post classic 250 and 350 two-stroke GP series – therefore there are rules! Love them or loathe them, rules keep the racing competitive and the bikes ‘in period’. We keep a keen ear on what our riders are looking for and there is a clear message that our kind of people want tighter period style machines. All our riders are on the same type of machine and the same Avon treaded tyres.
