Grinnall Scorpion III (original) (raw)
The Grinnall Scorpion III, by Grinnall Specialist Cars, is a reverse trike, with two wheels at the front and one at the rear, which is a better-handling configuration than one wheel at the front. Designed in 1991 by Steve Harper, the Scorpion III features a GRP body tub which is bonded to a space frame chassis underneath, and employs a BMW K-series motorcycle engine as its power plant. The engine, gearbox and final drive from the motorcycle are utilised with a special rear wheel which is fitted with a car tyre, as are the front wheels. It has a very good power-to-weight ratio which endows it with excellent performance. The rear wheel is of a smaller circumference than the bike's wheel so the gearing is optimised for a lower top speed of around 125 mph (201 km/h) with 0-60 mph (97 km/h) tak

| dbo:abstract | The Grinnall Scorpion III, by Grinnall Specialist Cars, is a reverse trike, with two wheels at the front and one at the rear, which is a better-handling configuration than one wheel at the front. Designed in 1991 by Steve Harper, the Scorpion III features a GRP body tub which is bonded to a space frame chassis underneath, and employs a BMW K-series motorcycle engine as its power plant. The engine, gearbox and final drive from the motorcycle are utilised with a special rear wheel which is fitted with a car tyre, as are the front wheels. It has a very good power-to-weight ratio which endows it with excellent performance. The rear wheel is of a smaller circumference than the bike's wheel so the gearing is optimised for a lower top speed of around 125 mph (201 km/h) with 0-60 mph (97 km/h) taking around 6 seconds when using a engine. Any can be used, from a 750 cc 3-cylinder, to a 1200 cc, 4-cylinder, giving power outputs from 75 bhp (56 kW) to 130 bhp (97 kW). The motorcycle sequential gearchange is retained and operated via a gear shift inside the cockpit and requires a forward or backward movement to change gear. The brake, accelerator and clutch operate as per a car and are adjustable for reach to accommodate drivers of different size. The seat and steering wheel are fixed in position. Handling is generally considered to be good due to the low centre of gravity and wide front track (approx 6 ft (1.8 m)) although care is needed when roads are wet. A turbo charged engine kit is available from BBR racing which increases power to around 300 bhp (224 kW; 304 PS) for an 1100 cc engine. There are two seats, and there is provision above the engine to accommodate some luggage which is roughly equivalent to two sports bags. The trikes are sold as complete kits with everything needed to finish including washers, etc. or as completed vehicles. They are essentially recreational vehicles which offer high performance but lack the practicality of a conventional car. In 2008 Grinnall offered the Scorpion III with the BMW K40 engine which Grinnall claim is producing over 167 bhp (125 kW; 169 PS) at the rear wheel. (en) |
