 Here is some more goodies from today.
 We set up a basic circle with a diameter of 12 feet and placed 4 cones at the 6, 9, 12, and 3 o'clock positions. We also set up a start and stop box. At first we rode 3 figure 8's between the 6 and 12 o'clock cones, then 3 between the 9 and 3 o'clock cones, stopping in the stop box.
 A video from Yamahammer.
 

Monday Cone Junkies


 We then changed it up a bit, riding a counter clock wise circle around the 6 o'clock cone, a clockwise circle around the 9 o'clock cone, a counter clockwise circle around the 12 o'clock cone, a clockwise circle around the 3 o'clock cone, a counterclockwise circle around the 6 o'clock cone and then finishing in the stop box.
 I'm pretty sure this will get used in the next Gymkhana event in Birmingham on June 16th. Its kind of hard to do fast as you are doing hard a left turn, then hard right, hard left, hard right. Getting stopped in the stop box is a pain too. :) the stop box is just 4 feet wide, 6 feet deep.

 Here is some video from that.

 Next up Yamahamer on a tarded Husky

 Now here is Pat on a KTM Adventure

 Here is Mulley on his new Aprilia Tuono.

 My fastest time was 43 seconds, fastest time was Yamahammer on the tarded Husky, 30 seconds.

 The XR1200 is a beast on tight stuff but its good practice. Thinking of tarding my Honda XR650L for this. :)

 Anyone got a set of 17 inch wheels that will fit it? :nanner:

 
It was a hot day but a good day!

The Cloverleaf looks like a very interesting obstacle, with your permission, I will add it to the Adachi System Obstacle Catalogue. The practice area you are using looks absolutely fantastic, we would be extremely lucky to find an area that good to practice on in the UK.

We would be honored - and as far as permission, if it is published in an open section of this forum - you can consider it open and public domain.

The lot is wonderful, the grade is perfect, as is the surface, and might even be as our regular event lot.  Needs a bit more shade.   8)

I really like the idea of course maps that help to standardize the elements.  Maybe this is what Mr. Adachi was promoting, and maybe not, but I think this can help promote our sport by allowing us to "compete" with each other, from remote locations because we can post times and compare our progress.  Most excellent.
Lean into it...

Its a circle with a 12ft radius. Cones were placed at the 12, 3, 6, and 9 o'clock positions. Or maybe it was a 12 dia. :) Mark should know for sure.
 What I think would be cool would be a decressing radius turn leading into the cloverleaf then lead out into a incressing radius turn. (like the last event). Of course we might need a puke bucket in the stop box, that's a lot of circles. :)

Pretty sweet I wish I could have made it. Been working on a big job. I will have to shoot some pictures of it or a video. Then I get to start on another one tomorrow.

For most of the obstacles (apart from the GP8) in the Adachi System Catalogue, the exact dimensions and distances between the pylons are left pretty much for the course designer to decide. However, as we are getting a lot of feedback from people all around the world to have more comparison obstacles than just the GP8, we will be looking at taking some of the obstacles and maybe even a complete course and working out some dimensions that could be achieved within a reasonable area. We have an event at Dunsfold in Surrey this weekend, so I will lay out a Cloverleaf to the dimensions you suggest which is four pylons placed at 90 degree intervals around 24 foot diameter circle with a start/goal box located 12 feet away from the first pylon in the set. I will ask our local riders to give it a try after they have finished the competition and let you know what times they manage. I will try and shoot some video of it as well.

I have attached the Cloverleaf diagram that I have just entered into the Adachi System Catalogue. It is without dimensions, but if our little experiment works then I shall get a special one added.

After chatting things through with various people on this side of the pond, somebody suggested that the Cloverleaf obstacle would be much easier to do if it was made as an extension of the normal GP8 course. Simply add two more pylons the same distance apart as the GP8 pylons and at 90 degrees to the two existing ones and hey-presto, you have an instant cloverleaf! This will save much messing about with marking and measuring as most of the job has already been done.

 That's how it came into being. :)
This was not a planned out course, it was more, "hey, let's make it biggger". At first we ran it like 2 GP8 courses then went to circling.

Our chaps just couldn't wait to give the Cloverleaf obstacle a try. Here Jonathan Morris has a go on his way home from buying cat litter.

 Cool!
I have been wanting to add to the cloverleaf.
1. Do not have the start/stop box, instead;
2. Lead into the clover leaf with a decressing radius turn
3. Run the cloverleaf
4. Lead out with an incressing radius turn.
5. Start box at the beginning decressing radius, stop box at the end of the incressing radius turn

 I want to try that lay out in the coming weeks. Want to see what works best in getting the 3 parts to flow together.
A decressing turn bits a lot of riders on the butt on the street.

Sounds good, will give it a try, but remember for timed obstacles the start and goal boxes must be quite close together. Would suggest that using the current pylon layout, rather than going from start into a rotation around the closest pylon, ride around the outside to make the first rotation around the pylon opposite start/goal. That is a mighty tightening turn for anybody to manage. However, tightening turns are no problem if you approach them nice and slow. To get the best effect, riders need to be hammering along at a fair lick, before the evil course designer draws them into a decreasing spiral.  A tightening turn should be do-able within the 'normal' control envelope (even though few riders can manage them) so they are best left to be included in with a course layout. This is why the international timed challenges such as GP8 focus on particular skills that are outside of the 'normal' control envelope such as full lock rotations etc.
