Although the engine displacement is only 30cc but can already go 40kph. The manufacturer is the same that build excavators and heavy equipment, so probably they put the same materials in this engine.
The website is still up. I bought this off ebay a few years ago and I'm ready to do a build with it. I'm going to use a Jamis Earth Cruiser bike and a 8spd. internal hub on the back. Hoping to use gearing to get top end stretched out to maybe 35mph.

If this needs to be a build thread let me know. Just want to keep this on the BE30 Komatsu area. Nuvinci N360 needs to be 135mm so with a little old school thinking and a fence post.
