At BoostBusters we enjoy ICE:s and ICE-driven vehicles in general but it is more cost and space effective with two wheeled motorbikes than cars. A road converted Enduro bike with a two-stroke engine seems to be a nice city bike for the future.

The Suzuki Hayabusa is a lovely bike also without turbo. Bikes with fairing can have better use of 300 [PS] than naked bike but installation is tougher. The Hayabusa to the right use a stock 4:2:1 exhaust system modified into a 4:1 exhaust system unpstream the turbine. Turbocharger response is worse compared to a front installation and a compact exhaust manifold but sound during opened wastegate is absolutely fantastic!

This is Mjölner Hammer of Thor. At this point in time using a Suzuki GSXR 1000 engine and around 250 [PS]. It is amazing to drive a single seater behaving as a kart. Storing big turbochargers and charge air coolers is another benefit compared to a two wheeled motorbike. Mjölner is a motorbike and street legal. Center of gravity needs to be pushed to the front and as low as possible to avoid three dimensional driving. This have some drawbacks on comfort and traction...

This is Zandretti Mk1. It is very much Mjölner on four wheels and much more stable but also heavier. Added complexity is the sprocket differential and electric reverse. This was also street legal and classified as a car.

A Zundapp KS 125 was about the quickest 125cc bikes you could drive when I was young. This is the water cooled version from 1980 and one of the most beautiful bikes built.
