Motorcycle specifications Marine Turbine Technologies420 RR 2017 A cyclone between the rims

Put a helicopter turbine in a motorcycle. It always has an effect...
And yet, the MTT 420 RR isn't a first. In fact, it's the second. The descendant, to be more precise.

While traditional manufacturers strive for ever-greater performance within ever-tightening constraints, other enthusiasts, who could almost be described as craftsmen, let their madness speak for itself without worrying about the limits imposed. Having already stunned us in 2001 with the creation of theY2K, the fastest and most expensive motorcycle of its time powered by a helicopter turbine, Marine Turbine Technologie (MTT) is back with its 420 RR.

There's a 15-year gap between the two bikes, but the same excessiveness remains.
The basic idea remains the same: to offer a burst of horsepower and the torque of a Leclerc tank, based on a helicopter turbine. But as with any self-respecting Episode 2, we had to go even further. And hit even harder. The Y2K offered 300 horsepower. This 420 RR adds a good ladle of potatoes and announces.... 420 horsepower!
Forget references. Everything here is off the scale. The engine revs flirt with 55,000 rpm, while the advertised torque is 59mkg. If Maverick had swapped his GPZ 900R for this 420 RR in 1986, he'd have been chomping at the bit to take off with the F-14 Tomcat..

To withstand the power of the Rolls Royce/Allison turbine without breaking apart after a few minutes, the bike's architecture has of course been adapted. The perimeter frame is made up of two huge aluminum beams that not only support the reactor, but also contain the transmission fluids and 6 liters of reserve fuel!
Finally, the muscular wheelbase of 1727mm (24 cm longer than the Hayabusa) isn't all that extravagant when compared with that of another monster on the market: 2032mm for the Boss Hoss V8 and its Chevrolet engine.
Although it's almost reasonable, it ensures that the bike doesn't float away on first acceleration, thanks (above all) to the particularity of the swingarm, which is fixed high up on the chassis and provides more support for the front end. The choice of a horizontal monoshock was therefore essential.

you might say that the Boss Hoss develops 455hp, or 35 more than the 420RR. And doesn't this Mylliard, bitten by the Dodge Viper V10, boast 500 horsepower?
Yes, it does. But where the TT does much better is on the scales, and therefore on the power-to-weight ratio. Count 630kg for the Mylliard V10, just under 1/2 ton for the Boss Hoss (485kg) against .... 226kg for this 420RR. A real featherweight compared to other models of its kind! Carbon fairing and rims contribute to this performance

The peripherals, on the other hand, are heavy. Braking has been entrusted to Swiss equipment supplier ISR, which has chosen 6-piston calipers to slow down the rocket. A big 18" 200 gumshoe will be there at the rear to try to transpose all this avalanche of power onto the tarmac.

If you still have any doubts about the machine's performance, the manufacturer is content with a provocative statement: "Faster than you'll ever dare go". But we can already announce a top speed of over 400km/h.

In any case, remember its resolutely more modern lines than the cetacean-like profile of its predecessor. After all, you're not likely to come across a TT 420 RR in our neck of the woods any time soon! Forget Euro4 homologation (lol): it runs on diesel and kerosene, it's a serious glutton (the fuel tank is 34 liters!) and it howls like a gust of wind (check out those exhausts!).
At $249,900, the price tag puts this machine firmly in the pantheon of exceptional motorcycles.
