How do you run a DCT backwards on a steep incline when stalled?
« on: November 11, 2018, 08:39:17 pm »
I did an off road course this week end. One of the techniques taught with a manual transmission bike is to recover yourself when you have encountered a problem half up an incline when off road with poor traction. You stall the bike, switch the engine off and let it run backwards against compression using the clutch. How do you do it on a bike without a clutch?

 :sip: Surely you can use the front and rear brakes together and guide it down.  :bueller:

Iím talking about a reasonably steep incline, not good traction. Definely wonít work with back brake, you need both feet on the ground to keep bike bike up right. Would be good to get an aswer from somebody that had done it in practice

Park brake. Using the clutch/gear is also just on the rear wheel

Thats my guess  :peepwall:

Itís not the same- youíre not running against engine compression.

How would you stall a DCT? would it just not stop and idle if not enough throttle demand to pull off up hill..

Edit..

If you cannot go uphill anymore due to traction i suppose you are stuffed.. no engine braking going downhill backwards..

Does it have a linked braking system that brakes front and rear with the (Handbrake) lever?
My Gs does it.. both feet on the ground using front brake it stops the rear wheel aswell.

Only solutions I can think of is to feather the front brake or turn the bike as you are reversing back until you can ride down facing forwards

Right on.

Even if the engine is only idling and it is in 1st, you still will not have any torque at the rear wheel at idle. The clutch only engages once you lift the revs. Once the engine goes to idle or stops the clutch disengages.

To get around the issue, use the the park brake. It's where the clutch would normally be. You use it like you would on a bicycle to control the rear wheel.

The reach for the lever is quite large to prevent people, out of habit, pulling it by mistake, but it's not impossible to manage.

There is one anomaly related to hill starts that sometimes happens but it is very rare and hard to repeat.  It is possible to stall the bike in say 2nd or 3rd gear. I've seen it happen only when the bike was dropped whilst riding..The engine is now off and the gearbox is "locked" in that gear and now you can't move at all and the bike cannot be started. This wouldn't be helpful if you are on a steep hill. With the ignition on, you have to rock the bike backwards and forwards a little and the bike will free itself up to be started.

I wonder where that gravel road goes? And that, has usually made all the difference. (Apologies to Mr Frost)
