Holeshot device for ur race bike?

I spent a lot of evenings at the local drag strip with my street bikes during the years before I started doing track days. Never had to replace a single clutch plate. And I was getting pretty good times. Probably could have gone a c*nt hair quicker by not taking good care of my bikes, but it wasn't worth the trade-off to me.

 

I love u guys!!

 

Ok, my lack of experience with motorcycles (and the fact that i have never even sat on a dirt bike) is showing........because i have no idea what this thread is even about.

When he said "holeshot device", i assumed he was talking about launch control.

 

Chris, if you ever watch an SX race on TV you will see th riders and mechanics push down on the front end at the start line. They are locking the front end holeshot device. It pulls the front end down and holds it (much like drag racers use straps to hold down the front end on street bikes). It makes the bike easier to launch and less likely to wheelie.

when they hit the brakes though, and compress the front end, the device lets go (where drag race straps stay strapped). So it helps the launch, then does nothing the rest of the race

 

am i the only one thinking about how slow you would have to putt around on the warm-up lap?

 

Wouldn't matter. You'd be off the bike by turn 2 anyway.

 

While we are on this whole launch control/ holeshot topic:

is there a list of bikes that comes with launch control from the factory?
which kit ECUs have launch control as an option?

Been curious about that for a while now.

Thanks

 

exactly...the bike would be nearly un-rideable when it came to actually turning.

I've ridden a bike with straps, it sucked doing anything but going straight. There's a reason motogp and WSBK don't use the holeshot setup from a dirtbike.

 

roadrace bikes have 25-35mm of sag, stiffer springs, and lower center of gravity. Dirt bikes have 100+mm of sag, softer springs, and a much higher center of gravity. These things make a wheelie way more likely on a mx bike. The obvious has been pointed out that ya can't have a dozen people rush out to the grid following a warm up lap to assist in latching the holeshot device. Holeshot tabs are tough to lock by yourself on a mx bike, it would be impossible by yourself on a rr bike. RR bikes are on the verge of nervous already in regards to geometry, a warm up lap with one already locked down would be pretty scary ..
Good throttle and clutch feeding can make for some good 60' times without pulling the front down a couple inches. Yes, they strap the front down in drag racing, but if all goes well ya don't have to make any turns during the pass

 

Thanks for the explaination Joe :up:

Cool idea for dirty bikes, not so much for ours.
