12 meters is around 39-40 feet.
3 meters is around 10 feet.
1 meter is around 3 feet

These are the dimensions I've been setting up. We haven't been concerned about cone height here in NY, as we've been using the low ones, and they are about the height of a cut tennis ball.

However taller cones do make a difference, as you have to account for that height when you are turning really close to them, in order not to knock them over. Since I'm carrying all the cones I need (around 300 of them) in my saddlebags, I opted out for the shorter ones since I can pack a lot of them, plus our location can get windy and tall ones start sliding around with gusts.

Just had this video of one of the riders in the Viet Nam Moto Gymkhana group attacking the course on a B-King!

Just shows what you can do on a big, heavy bike.

If only we could use these hilariously oversized pylons again lol.

Any video with a bigger bike? like a Hayabusa or Goldwing going at the same pace

That is fantastic!

I'm always amazed at how we end up puffing & panting, hearts racing, when we practice. Glad to see it's universal. That guy is buzzing.

That was quick! He also made pretty good time dismoumting and showing his time.

I was out at an ohv park yesterday and we set up GP8 in the dirt.

Son with little riding experience enjoyed it and wants to do it again..

His best of three was 55, mine was 45. I'm not sure what approach to take, as I can't quite get my drift on to swing the rear around, and my speed was too fast to make a tight turn.

He was making much sharper turns than me, much better form.





I've marked out a few practice spots so I can practice on my way home. I superglued shiny pennies to the tarmac, so only have to drop some halfballs on top of them.



Finding an ideal spot that is good for a group is harder than I thought.

Great video of that guy running a sub 26 sec

Also was interested in his self timing setup, with professional timing equipment being so expensive, I have a few questions for you tech heads. He seems to be running a light beam? switching the lap button on a modified conventional stopwatch. Does anyone know how he did this?

Alternatively, I was also thinking how difficult would it be to build a portable retro-reflective visible laser (TX & RX in a single unit) bouncing the light off a reflector, when the bike cuts the beam it would start the clock, second time it cuts the beam stops the clock. O/P of the laser to a simple timing program on a laptop. Then displaying the laptop screen to a TV via HDMI output, so everyone can see the recorded time. I would use a small portable generator for my power supply.

His stopwatch from the video

Been meaning to build this for our group, but I never touched a soldering iron before in my life... But there is a first time for everything.

Didn't you get that lap timer? Pretty much same idea, with convenience of the timer being mounted on your bike, so you don't have to get off to see how well you did.
