Honda working on a 400, MTT working on a turbine bike.

Whether you want a practical commuter that’s still a little fun, or a full-on hyperbike, you can have your wish granted.

Hell for Leather is reporting Honda is working on a new 400 cc range of motorcycles, built around a short-stroke version of their 500 cc motor (announced in late 2012). That half-litre parallel twin powers the CBR500 sportbike, CB500X adventure tourer and CB500F naked bike; supposedly, the new 400 will power a similar lineup of machines.

While Honda says the new motor will be proportionally less powerful than the 500, it’s possible the shorter stroke will allow for higher revs. It will be interesting to see where this project heads – it’ll likely be a sober commuter, similar to the 500 series’ professed intentions, but if it’s a bit more nimble or the motor is more rev-happy, this bike could be fun.

But, one thing’s very likely – it’s probably not headed here for Canada. With their 250s and 500s already in place in the Canadian lineup, the 400s will likely stay in the Asian markets, where countries regulate and tax larger engines – 400s haven’t sold well in Canada in a long time, and Honda knows that.

What about the hyperbike, you ask? Well, Marine Turbine Technologies (MTT) is announcing a new turbine-powered motorcycle. It’s not the first time they’ve done this sort of a project; they built the Y2K motorcycle (as owned by Jay Leno and seen in Torque).

Faster and Faster says the new bike is supposed to be built around a Rolls Royce C20 gas turbine, putting out 420 hp. That’s 100 hp more than the original Y2K, so owners who found that bike a bit slow can now really put all their high-speed skills to use.

The new machine has a carbon-fibre fairing and wheels, and aluminum chassis. Brakes have been upgraded from the original Y2K, and the new turbine bike has ABS.

Supposedly, the new bike will be available mid-summer, and will likely cost an arm and a leg – the previous Y2K cost $200,000.
