Video of a 4 Stroke Valve train
« on: February 18, 2010, 06:31:54 AM »
Holy cow!! No wonder these these go BANG in a big way!

BMW S1000RR Technical Video - Valves in Motion High RPM

This is a video of a BMW at 14,500rpm.... it's just warming up until about the 1 minute mark, but after that things really get moving.

When the smoke started I was thinking that it was going to explode.

That's really scary.  I just drove home from school using one of those things, man!  I need to get an old 2-stroke Saab, like, now!

Is this Maico a 440 or only a 400?  Well in all the confusion, I forgot myself.
But considering this is a 1978 Magnum, the best-handling bike in the world, you have to ask yourself one question.
Do you feel lucky, punk?

Mergerz - share the link from MX UK.... it'll be fun to see what the folks in the UK say about this stuff.

Jetzcorp - The one good thing about the machine that you drove home is that it probably did not rev beyond 5,000 rpm... so yur safe! :P :P

Anyone else notice this video got removed from all of existence?  I guess BMW realized that it was scaring the bejesus out of people.
