ACU Announces Changes to Isle of Man TT Sidecar Regs - Supersport Rules, Three-Cylidner Engines Now Allowed

The sidecar class at the Isle of Man TT is about to get a pretty big change, as the ACU has announced a shift in the sporting regulations for sidecars. Already opening up the engine spec for the 2014 Isle of Man TT, the governing body has once again modified what the three-wheelers can use for their engines.

Applying the solo-class Supersport engine specs to the sidecar class, teams will have more strict guidelines on what they can and cannot modify for their machines, but they will also have greater flexibility in what engines they base their racing operation upon.

Since the Isle of Man TT Supersport class allows for 675cc three-cylinder sport bikes to compete, Sidecar class entrants can now make use of power plants from the Triumph Daytona 675 and MV Agusta F3 sport bikes.

A sort of an oddity at the TT, sidecars still manage a cult following every fortnight (mostly by zie Germans).

The push for “F2” class rules into the TT racing format could help bring more fans for the non-solo racers, and it certainly will bring another racing dynamic to the TT’s two sidecar events, as more traditional teams compete on their four-cylinder 600cc sleds, while others try their hand at triples.
