Awesome photos!!! Thanks for posting these.

Today was a loooooooooooong session. Two groups of riders, scorching heat, high humidity, but sticky tires and good brakes

We had 10 riders in total on the course today. You guys are awesome, a joy to ride with you all.

Setup?

I've read the thread with fascination. Didn't know there was such a sport but it looks like the kind of stuff that I practiced (mildly) when I was learning to ride and seasonally now.

Is there info someplace (in English please) on how the best Japanese competitors setup their bikes?

I see oversize sprockets in the videos which likely are so they get the best performance in a single gear.

I wonder about the front suspension.
Would having soft front springs and short stroke so that it bottoms quickly and stays there (or has very slow rebound) be helpful? Surely suspension is part of what they modify?

great shots! thank you for taking the time and care.

could we throw these up into the Albums on the Groups fb page?
i'm thinking a centralized location for any session footage would be useful and convenient.

Too early in the growth of the sport here?

Not the most definitive on how EXACTLY to setup your bike, but general ideas.

I was watching that while you posted. Thanks!
What I got out of it was (1) larger rear sprocket is so that RPM doesn't drop too low while doing slow speed maneuvers (and thus you don't bog on exit) and (2) long-travel front forks such as for dual-purpose models have a HIGH spring rate so as to not compress much on braking. I presume that more road oriented bikes could do the same thing or could use soft springs to compress quickly and predictably. (3) They crash a lot in practice so the crash bars are extensive and seem to be pretty effective.

Fun to watch and even more fun to do. (I don't know how they remember the courses though...... I'm sure there's a method.)

Red cone = turn right
Blue cone = turn left

Red with yellow stripe = loop right around the cone
Blue with yellow stripe = loop left around the cone

Two yellow cones is a gate = go through

Yellow with black is a out of bounds.


Not too bad once you've done a few courses.

Hi Gripsteruser and welcome to the world of Motyo Gymkhana!

Many riders ask about bike setup when they first get started as it is quite clear from watching the videos of the Japanese riders that a lot of them have modified their bikes with different sprockets and increased front fork spring rate etc.

Our great friend Mr Kimura who is one of the leading specialists in the field says to "Fix the rider before you fix the bike!" By this he means that no amount of modification will help if the rider has yet to master the basics of the sport and in fact it is quite beneficial to have boingy forks and high gearing whilst you are learning the riding techniques as it gives you the greatest level of feedback as to how the bike is responding to your inputs.

Unlike trackday and short-circuit riders who always blame their forks/gearing/tyres/pistons/camshaft for their lack of performance the Moto Gymkhana rider knows that the only reason they are slow is because of their own lack of ability.

The sport was designed from the outset to be one which you could ride to the event on your road bike and ride home again afterwards without having to spend any money on performance enhancements as it is the rider that is being challenged, NOT the bike!

Just to give you a benchmark for when you should consider modifying your bike, the Japanese reckon that it is once you are consistently under 30 seconds for the GP8 and under 3 seconds for a rotation, until then it is best to leave the bike standard.

I totally agree with the approach to work on the operator first. I've seen it in several different sports.

Mine was an academic interest in that it's clear the top competitors in every sport will adjust their equipment for best results. It's nice to know what they do but I'm not going to modify my bike for this.

It's best to just 'run what you brung' and work up from there.

Just to show that it's the rider and not the bike that's being challenged, here Andi Beezley hustles a 50cc scooter around the Cumbria competition course.

His time was enough to put him in mid field ahead of some much more powerful machines.

we have a weekly (Thursday nights) gp8 now in birmingham, al.

keep in mind this is just some guys and gals playing in a parking lot for a couple of hours. useually the same people, nothing is timed (unless asked for) and its a lot of fun.

I'm hoping that through word of mouth, it will grow. the same people come each time, and a few extra unexpectedly. usually 8-12 people.

marks gopro capture from last week:

ill be setting up a google+ live broadcast for this weeks' too, if possible.

NO WHEELIES
NO ALCHOHOL
only two rules

there will be no harassment of the newbies!!! if you think you're a newbie, and are afraid someone might point and laugh, relax. we'll kick anyone that dares to bother you, all about the ears and shoulders with motocross boots.

you, mr/mrs/ms newbie, will be welcome.

meet behind beef o bradys at 7pm. we'll likely be there 2 hours or more, but unlikely to be much longer or earlier.

please, bring your bike, wife, gf, vbff, whatever, so long as they're interested in, and on, a moooooorsycle.




.....gp8- a simple figure 8 a rider attempts to traverse with smooth control and precision, on a motorcycle.....
