Shift RPM?

Yeah, they're badass.   Stupid power from a 2-stroke inline 4 with a light switch powerband.   

Then they mounted it in a 'dirt bike' chassis made of thin walled conduit.

I've had a couple of those come by me at Road Atlanta like I was standing still


....while running over 150mph.   Good god man, that sound at full honk in real life.

I'd love to put one of those engines in a modern chassis for a streetbike.


Watch the actual race from the 70's when he scared the living shit out of the Hardly factory team that was 'supposed' to finish 1-2-3.  That's a serious ass whipping.


"When they heard it, it was too late"   LOL

Kenny Roberts eh!. I bought a brand new 2006 R1 50th Anniversary Special Edition. Mint to this day with an original 6,500 miles on it. It's all original with the exception of a rear fender eliminator kit.

Before my time (And after his), but there's something special about this nasty nasty bike that was built solely to be nasty nasty.

That is the meanest sounding bike I have heard.

Period.

That's the meanest sounding bike ever




ever ever ever.


it's just straight up nasty nasty because it was built for one reason...   to be nasty nasty nasty.


...and those videos don't compare to real life!

It's also amazing just how old that bike is.

That's what the actual TZ750 looked like before Yamaha made a 'dirt bike' for the indy mile back when bikes and riders had to do all the events
