Kangaroo Hops

May I respectfully suggest that the solution might be in your right hand.  After all the RT is a large touring machine and not really designed for track day starts.  I owned a 14 RT for over 3 years.  Never experienced anything like the symptoms to described. And it has been pointed out this isn’t something discussed on any RT forum.

From the BMWMOA thread.

"I think there are two adjustments: the engagement point, and lever travel. The lever travel adjuster at the lever are to accommodate for example short fingers so you can decrease the distance the lever moves between fully pulled and fully out. If the engagement point is bordering on not fully disengaging the clutch for example when the lever travel is maxed, then it's possible if you shorten the lever throw you won't fully disengage the clutch. So they are related, but separate adjustments."

As far as I'm aware, there is only one adjustment, the lever travel. The adjustment of which, may impact on the engagement point.

Found this thread in Adventure Rider, http://advrider.com/index.php?threads/2 ... t.1050313/

JVB seems to be a bit of a Guru, and he says, "You can only adjust the lever reach."

Perhaps on this occasion, a BMW dealer would be better qualified to answer the question.

From the Rider's Manual.

Clutch
Checking clutch function
Pull the clutch lever.
The pressure point must be clearly perceptible.
If the pressure point is not clearly perceptible:
Have the clutch checked by a specialist workshop, preferably an authorised BMW Motorrad dealer.

Thanks I would agree with you perhaps if I was talking about arm fulls of throttle but I am not, at present I can only pull the bike away from standstill at a slow pace and can only increase power once the clutch is fully engaged, anything more than a slow pace results in the quite violent hopping.


I accept this is a large touring machine, the nearest equivalent bike I have owned was a GL1000 GoldWing which at 40 years old, a little heavier and half the PS would beat me away from the lights for the first 20 yards no problem with only moderate skill so something is amiss.

Was the bike sold with a 2 year BMW Motorrad Warranty.

Yes it was David so I will contact the dealership, with that in mind I will leave the lever adjustment as it is, thanks again for your help

It was this that made me wonder if you were pushing it a bit too much
I have started pushing the bike from a standstill now and then just to explore getting away relatively quickly.

Something slightly left field but are you applying the hill start assist? ( Pulling the brake lever had when stopped)  I find that if I have forgotten to release it prior to setting off  then i tend to get this hop whilst the brake releases

That's definitely not right, I can get mine away quite smartly without any special effort of technique.
You should take it back to the dealer and have it investigated and corrected.
- wrong oil
- faulty part/s in clutch
- faulty traction control
- faulty throttle/fuel injection parts/sensors
- the previously mentioned hill start assist, maybe it's faulty
