Novarossi introduce two new nitro engines specifically made for the use in 1/5th scale bikes. Designed in cooperation with Fabio Giovannini and Michele Repetati the rear exhaust engines cater for the needs of bike racers with the BK15 being a 2.49cc engine with 5-ports, 6.5mm slide carburettor and 11.5mm turbo crankshaft. The short stroke engine uses standard steel front and rear bearings and a turbo-type glow plug.
The second new engine is the smaller BK12 with a displacement of 2.1cc. The long stroke engine features a 3-port setup, an 11.5mm crankshaft and a 5.4mm carburettor. Like the BK15 it is designed for the use with turbo-type glowplugs and 16 percent nitro fuel.
