I have a friend whose team is a world record holder at Bonneville. For the most part drag and traction are the biggest gains. In fact they add weight to the car to ballast it and gain traction and handling over 200 MPH. It's a different world of 200 MPH, and there isn't a lot of traction on the salt. You literally hydroplane on the wake of salt the builds up on the leading edge of the tires, because it can't dissipate at the higher speeds. If you watch the amount of steering input at speed, it's incredible. The same amount on pavement would turn you 90 degrees in a heartbeat.

My CBR spins the tire at 4000rpm in 4th on the salt, I was amazed at how slippery it is. A friend is part of a world record team (272mph on a bike) and he said 10% wheel spin is about the average at speed?  here is an article about Joe.  the guy he mentions at the end (Stacey) is an interesting guy, I have a beer with him a couple times a month..

the above opinion is simply that of an average middle aged hick with one too many brain injuries... or, don't take it too serious.

Weight = lost power.  Ideally, every ounce you can strip off the bike and rider = more power into pushing to faster velocities.

I'd think an overweight rider would rob the bike of it's full potential.


Only because an overweight rider = bigger = less aerodynamic.

His flabby, slimy tail would add quite a bit of drag, I suspect.

At Bonneville, on OUR bikes, my brother and I found that he could get slightly better top speeds than me. He weighs probably 15 pounds less than me.

But more weight isn't necessarily a bad thing. A lot of people at Bonneville put lead ballast in/on the swingarm (seriously!) in order to reduce wheel skip and be able to more efficiently put power down to the salt surface.

The best pure way to go fast there is to make your bike as aerodynamically slippery as possible. There are naturally aspirated 600 cc bikes running over 190+.... but they always have extremely customized fiberglass bodywork. And not every class allows custom bodywork either.  Thumbsup

Nice video! Thanks for sharing.

Love the title of the thread! I don't want to ruin the ending for those who didn't see it yet!
