New British Spirit Motorcycles unveiled

Spirit Motorcycles GP Sport R

British company Spirit Motorcycles has entered the motorcycle industry by launching not one but four new MotoGP-inspired models with a Triumph triple engine.

The GP-Sport sports bike and GP-Street naked bike start at £44,999 ($A75,000), while the limited edition GP-Sport R will cost £64,999 ($A110,000) and the GP-Street R £69,999 ($118,000).

They join a growing trend for esoteric and expensive bespoke bikes for the rich and well-heeled.

This includes the recent limited-edition Norton four-cylinder V4 SS which sold out at £44,000 each (about $A74,000, $US55,000) and the V4 RR models costing £28,000 each (about $A47,000, $US35,000).

The Spirit Motorcycles come with carbon fibre bodywork, F1-style electronics, K-Tech suspension and a MotoGP-styled fully adjustable chassis.

They say the trellis frame is brazed rather than welded so it can flex lime a MotoGP bike.

British power

Spirit Motorcycles are powered by a Triumph 675 triple stroked from 49.6mm to 55mm to 750cc. Compression is increased to 13.5:1 on the standard models and 13:8.1 on the R models.

Power is up from 93kW (126bhp) at 11,900rpm to 116kW (156bhp) at 14,200, while the R has 134kW (180bhp).

Wet weight is 150kg for the standard and 145kg for the R versions.Spirit Motorcycles GP Sport R

This compares with the Norton V4 models powered by a 1200cc, 72° V4 with at least 150kW of power at 12,500rpm and 130Nm of torque at 10,000 revs. However, it’s a lit heavier at 179kg dry.

The Spirit Motorcycles models are the result of a collaboration between custom builders Spirit of the Seventies and Tony Scott of tuning firm T3 Racing.

Electronic connections

The R models have some fancy electronics that monitor and control an amazing amount of bike dynamics and will transmit them all on a 4G phone sim connection with Spirit Motorcycles.

After your track session or race, you can phone the company who will suggest adjustments, just like having a personal race engineer.

There is no word yet on whether the bikes will be available to overseas markets, but they will be limited to 50 models each.
