Custom-built Suzuki SFV650 Mini Twin Racing & Track Motorcycles

An affordable route into competitive motorcycle racing.

JHS Racing create bespoke, hand-built racing motorcycles that equip you with a highly-competitive but affordable foundation for participating in both club and national-level road racing.

Our broad experience with the preparation of racing motorcycles extends from British Superbikes to competing at the Isle of Man TT. For over a decade JHS Racing have been developing and racing with Suzuki’s SV650s and, more recently, the SFV650, notching up a cluster of race wins and lap records with these machines.

Our Suzuki SFV650 Minitwin racing motorcycles are supplied fully regulation-compliant and ready to race, with aftersales telephone support (during normal office hours) for 1 year.

JHS Racing Suzuki SFV650 RR Minitwin:

The Minitwins series impose stringent guidelines. Working within these, we take a brand-new Suzuki SFV650 and strip it down to the frame. The frame is then de-lugged and is re-lugged as required. As per the Minitwins regulations the engine remains completely stock, to comply with the 72bhp limit, and is offered back into the frame.

The standard loom is modified and all of the road-based wiring is removed, which also sheds weight. A racing air filter is fitted and a Power Commander V installed, in combination with a custom map.

The forks are stripped and a K-Tech 25IDS kit is installed, while a K-Tech 35DDS shock looks after the rear of the SFV. There is a meticulous attention to detail throughout, including captive wheel spacers to aid wheel changing, plus a host of other racing necessities incorporated into the package.
Other features include:

  • JHS Racing GSX-R600 fairing
  • JHS Racing rearsets
  • JHS Racing clip-ons
  • JHS Racing fairing brackets
  • JHS Racing exhaust
  • Pipe Werx end-can (102dB without baffle, 98dB with)
  • Avon tyres
  • Q/A throttle
  • Hel brake lines

Prices vary based on actual build specification requested.
