UK Thunderbike For Sale

Our eBay mole, Kev H, alerted us to this Honda 500 for sale. on UK eBay with a classified ad price of £3500. Below is the advert blurb. It says it raced successfully in the DTRA. I can't ever remember seeing this racing, but that's not to say it didn't. Successful? That might mean it finished the races it entered. It certainly wasn't on the podium. I guess it depends how you gauge success. Anyway, it looks ready to race and not a bad price for a framer if the engine is good (and obviously I don't know). It has nearly new Maxxis tyres on it. Great fro practice and first two rounds of , then the owner will need to swap for Dunlops if they want to race in the DTRA.

It says the chassis is a Boss frame, which isn't the best known, but is a genuine US framer. I raced a Boss CR250 at The One Pro Races in Salem last month and liked it. Anyway, here's the advert. I think the bike is located in Wigan, Lancashire.

Here’s a chance to own your very own genuine American flat-track bike! It’s complete with the original sponsor stickers.

The bike has been owned by myself since 2014.

Raced successfully with the DTRA in their thunderbike class

Details about the bike:


  • Boss nickel plated frame with box-section swinging arm with three shock mountings

  • Barnes knock-off hubs

  • New adjustable Hagon shocks

  • Bultaco forks

  • Grimeca rear brake & master cyclinder

  • Maxis flat-track tyres in good condition

  • There’s no kick start but starts well on rollers


  • XR500 heavily tuned including 540 WYSCO piston

  • Bespoke Quill exhaust

  • Mikuni flat slide carburettor

  • K&N filter

This is a genuine 30-year-old racebike from the USA so it’s has some knocks and scraps including

  • Frame has had a repair at sometime, probably whilst in the states

  • There is a broken tap in the head steady on the frame

  • Minor stripped threads on the engine, that should be easy to repair, but because the engine is OIL TIGHT I haven’t bothered

Retirement forces a VERY RELUCTANT SALE, and its ready to race with a few spares.

Any questions just ask - thanks looking - possible delivery
