Nothing here is going to disturb the BMW engineers' sleep. Still an OHV design, but this one apparently uses one push-rod to move two valves via a bridge. It seems to me like this has been done before. Here is a link to the story: https://www.motorcycle.com/mini-features...ine-design.html
Current motorcycle collection: 2002 Yamaha FZ1; 2005 Triumph Bonneville T-100; 2011 Royal Enfield Bullet 500; 2009 BMW F650GS; 2016 BMW R1200RS; 2018 Zero S 16.6 kWh

Zitat von Richard230 im Beitrag #1 Honda "Güllepumpe" CX 500 - but with a differrent approach:  "It is often said that before you die your life passes before your eyes. It is in fact true. It's called living." |
