Why won't you damage your clutch from doing that?

Why are Japanese riders, even with new technology, still ride without slipping the clutch?


And seriously... it slipped your mind, to share this?
The way I describe it - is brake and "throttle/clutch"

I combine throttle/clutch as a unit, as it is really power/torque vs. brake.

The combination is dependent on your setup, bike skill level, etc.

Some folks can ride around on motards with huge sprockets never using the clutch at all.
Others need clutch to get the full benefit of power from the bike in the gear they choose (they may not need clutch in 1st but may need a lot in 2nd gear)
Slipping the clutch while dragging the brake, or simply having lots of power wound up behind a brake that inhibits that power.

Duncan may be better at explaining it than I am, but for me, it is the primary component of gymkhana.

It makes ALL the difference to new riders, and creates the AHH-HA!! moment, when they realize that this combination will allow them to turn their bike in full lock, even at 2 MPH (3 KPH)

I hope to create some "Balance" tips & tricks very soon, but wanted to introduce the idea 1st.
The brake, throttle/clutch concept is essential for beginners, just getting started.

I put together another video weeks ago, and tucked this one away, then forgot about it

Wow! Some serious lean angles in the wet by our Ukranian friends, maximum respect.

The 'do I use the clutch or not' question has many answers, but its use really depends on the power delivery characteristics of the bike. For a good example we had a chap turn up on a Yamaha TDM 850 and no matter how much he tried to balance the throttle against the brake, the engine would bog down and nearly stall. Adding a bit of clutch to smooth out the power pulses fixed the problem. It means that this fellow now has three controls to manage, but at least he can now maintain a suitable amount of driving force without risk of a stall.

I ride a TDM 850 MKII, standard exhaust restricts the engine at low revs. Mines a noisy bugger, open Kerker pipes.. When I started this I used the clutch a lot, always had it covered. Now that I am getting my head around using the back brake to control speed & have the confidence to keep the throttle open, the bike is happy. No clutch. Biggest problem is getting on & off the gas, those big pistons can be abrupt both ways.
If I can contribute my thoughts with the TDM in any way put us in touch. Or the rider can explore HERE. I am posting about Gymkhana on the forum but getting very limited interest. Great forum & riders nevertheless.
My bike pulls from just above idle so my biggest problem is lack of engine bars & lack of skill. The bike never fails to amaze.
Niche bike, niche sport

Agreed! Mad props to our friends in Kiev! Those would be impressive photos under sunny, blue skies. Lean angles like that in the rain?!?! Well...I've got a ways to go, obviously! :)

Regarding the earlier comments about getting the rear tire to slide out a bit under power: I've gotten my rear tire to slide out a bit in the rain on the streets a couple of times (not in gymkhana, except for that one time in the second video I posted here), and, well, I've mostly recovered from the experience Honestly, the Shinko 705 I run is great in the dry, but does have a tendency to slide in the rain. On the plus side, it recovers with very little drama so I'm learning not to get too excited when I feel the back end start to slide on me.

Eh? Look again, it's the female reproductive system..


Re Shinko 705, yup, not the best in the rain. The only slides I've had have been in the same circumstances.

You guys have really been inspiring me to get my practice in. I even got some pavement gymkhana practice in last night.

Video from today's practice session.
Spills: YES!
Thrills: Maybe
Chills: Not so much.

Thanks, once I get the crash bars on this thing, I'm going to find me a nice clean parking lot.
