A TSS RS500GP being put through its paces in New Zealand

The RS500GP is here: THE Two-Stroke Superbike. Developed by a 500cc GP engineer for maximum thrills AND durability, this is the most exciting lightweight, high-powered sportsbike for street and track and it is available to build or purchase anywhere in the world.

With 120HP at the crank and weighing just 108kg wet (in race trim), this is one explosively powerful and telepathically nimble machine. Ridden well, the RS500GP can run rings around modern 1000cc four-stroke sportsbikes, while delivering more thrills in a lighter, more responsive package.

This short video was shot in New Zealand. More videos will follow from Australia, the UK, US, Europe and of course The Isle of Man.

At which engine speed does this engine produce its peak power? The Yamaha Banshee engine it is based on produced maximum power at 7,500 Rpm. Have the port positions been modified (for the cheetah cylinder) to produce best efficiency at a higher engine speed?

[twostrokeshop]

Peak power is 112HP @ 9800rpm. The cylinder porting has been customised by 500GP engineer Wayne Wright for this road/race application.

Amazing, nothing better than a powerfull 2stroke. hope they will get a thing like it in production, then i will buy it.

[twostrokeshop]

Hi, yes these are in full production, for road and race.

[juleol99]

Love it! What is it about the sound of a well tuned two-stroke? I do not know, but I do know I cannot rest until the day i have one of these of my own. This one does not sound very high rev'ed for a two-stroke though, it sounds more torqy I think. And is this the 90 degree crank we are listening to ? It love to see more flat out drive-by videos, and perhaps onboard with good sound too.

[twostrokeshop]

Yes this is the 90 degree crank, which explains the deeper engine note. We also build engines with 180 degree cranks, for that classic high-pitched two-stroke wail!

imagine a 1000cc 2stroke bike

[31ufo]

Congratulations for Yours job, but the conversation is to much expensive... 2stroke forever!!!

[BeeeAitchPeee]

Is there any footage of the 180 crank version anywhere to be seen? And what DB levels does the RS500GP run at? As most UK trackdays have strict noise rules now. Speaking of which is there any UK approved agent/dealer??? PS - an utterly gorgeous creation. Quality, emotion, evolution, desire all have been skillfully entwined in this work of art screamer. A credit to the creators indeed.

1. New Zealand looks like a bikers heaven.

and;

2. I FUCKING WANT ONE.

Is it just two 250cc single cylinders stuck together?

Either way, bring back two stroke power.

So much better than 4 stroke for performance!

omg!!!

[vrednie]

@tkubecek An R6 would have ZERO chance up against this thing. Have a look at the power to weight of this thing, and you will see what i'm on about

[acidangelster]

Please Tell Wayne Wright that he s has a special place reserved for him in Heaven,cause god s a huge fan of two stroke monsters.

[bogboy22]

Hey, Hows development going? Have you had it for a run on track? Great sound to it I must say

[tkubecek]

@twostrokeshop

hi i was wondering how this engine would go up against a yamaha r6?

involved in speedway racing and looking for something to destroy these worked r6's which a dominating our sport...

[PainKiller3231]

I can only imagine what the powerband feels on that thing.
