Video: Two-Stroke Engine Spinning At 20,000rpm Will Make Your Head Spin

A two-stroke engine at work is a thing of beauty. Nitromethane powered two-stroke engines though are in a league of their own as they can rev incredibly high - sometimes even as high as 50,000 rpm.

Youtuber johnnyq90 designed a plexiglass crankcase cover for a nitromethane powered R/C engine to let viewers see what the crankshaft looks like when the engine is spinning at around 20,000rpm.

While the video does show you how to create the plexiglass cover, we would recommend that the hardcore two-stroker speed ahead to the point when the engines revs into life. The spinning crankshaft is too fast for the eye or even the camera to capture and shows you just how hard an engine works at full chat.

Two-stroke engines are considered to be a thing of a past but if you really want to hear an engine hard at work you need to go to the race track or get on sports bike like the Yamaha R6 which revs up to 16,500rpm. Click on the image gallery below to see the latest images of the 2017 Yamaha YZF-R6.
