According to the guys over at Autocar, LA-based Marine Turbine Technologies (MTT) are now developing the next generation of its Y2K Turbine Bike, which was first launched way back in 2000.
The new 2013 MTT Y2K gets new engine and a number of updates. Compared to the previous model with a Rolls-Royce Allison Model 250 engine – this engine commonly used in helicopters – that produces 320bhp at 52,000rpm and accelerates from 0-200mph in 5.4 seconds, the 2013 MTT Y2K 420R hyperbike has 100bhp more power thanks to its Rolls-Royce C-20B gas turbine engine that mated to a custom-made two-speed gearbox and bangs out 420hp. The new hyperbike is currenty undergoing wind-tunnel testing in the UK, and MTT claims it has a top speed of 260mph+ (418km/h).
Other upgrades include new carbon-fibre wheels and fairings, larger 240 section rear tyre, and radial-mounted calipers on the front brakes with ABS.
The MTT Y2K hyperbikes run on diesel or A1 Jet fuel.
