Dyno machines

[marsmax85]

I've been to few bike weeks now and there's been some dyno machines there Are these legit? I remember reading the sign next to one dyno that they only run up to 4th gear . There was like 3 different categories also for testing can't remember what sign said I should have taken a pic and posted .Any thoughts are appreciated !!

The one that I use will only dyno in forth. The operator said that its a safety issue. On a Vmax in 4th at 9500, the back tire is still running at the equivalent of the high 120's to 130 mph.

Most use 4th because many sportbikes now have the capability to exceed the roller safe limits (200mph).

Thanks for heads up just wasn't sure about these mobile units I see at these events.

The local shop will generally dyno in top gear, unless it is a bike that will get that wheel spinning past safety limits. I know Woona was run in 5th when she had her pull on the machine.
