Hill start

[SBD]

I use mine lots, and I reverse downhill into the garage every day without any problems at all.

Maybe I’m incredibly lucky, or incredibly skilful, or yours is set up wrong, or you’re using it wrong.

Yes same as SBD never had a problem comes in handy when fully loaded & stuck in traffic when facing up or down hill

Hill start saved me from dropping the bike yesterday. Definitely wouldn't have saved it without as I was going up a steep dirt track with no chance of a u turn outside the farmers house. Managed to back it down gently and turn round where he parks his vehicles.

Similar tale for me last week. I had parked my van a little too close to my garage door and as I weaved my way up the steep driveway around the front of the van I somehow cocked up the biting point and rolled back whilst leaning off the bike. The hill start caught the bike as it rolled back, allowing me to heave it back upright just as it tried to fall over.

Without the assistance I would have definitely dropped it. I was previously a skeptic but now I’m won over by it.

Anyone have an idea why the HSC works fine when bike is in neutral but when in first gear comes on momentarily and then off again?

Hill start assist is a solution to a problem I never had.

Indeed it is.
It came on my KTM as part of the electronic package. I turned the bloody thing off on day two of my ownership six and a half years ago. Foot on rear brake, Few revs, clutch gently out whilst feathering the rear brake. Never had any issues with that way of doing it. but certain nearly dropped the bike when the fecking thing wouldn't release as quickly as I would've liked it, resulting inmate stalling the motor.

Mine doesn't. Maybe because you are engaging one of the brakes.

No - brakes are off - just applying pressure to engage HSC - works fine in neutral but not in gear

Something wrong there. I use it a lot whilst in gear.

Yes previous bike it's worked fine - just wondering if there is some switch in clutch / gears that effects it

 

[Mart75]

Well - clutch switch fault code came up with the motorscan - so thinking that this maybe the issue - most of info via google search says that the clutch is not part of the HSC system - but found this explanation via google search regarding clutch switch. So - think I am going to check / replace the clutch switch.

I was going to ask where you got that info then saw the snippet of `AI Overview` in your pic so asked the question myself.
Good old AI/Google - ask it one question and you`ll get a thousand answers - all different.....



I do however think that the switch does play a role in the release of the brakes.

 

[Mart75]

Yes - I think Google comes up with a no to the clutch switch most of the time - but given the problem on my bike ie works when in neutral but not in first - clutch switch being involved makes sense

 

[Hann]

Yeah, i can`t see the hill hold release being based on the ABS wheel sensors, that`d mean fighting the calipers hold on the discs until movement was detected which is surely not very sympathetic mechanically or the best way to go about it, sensing when the lever is being released via the clutch switch (plus sensing increased engine speed/load?) seems the most effective way to design it.

Mine works fine, you can even tell the difference when holding on various gradients - barely noticeable release when level but much more engine speed/power required when on a steep incline. It does pay to wait at the `bite point` for a second or so until you feel the release to avoid any embarassing stalling potential, though.

Well final update (hopefully)
So despite the majority of online info saying that clutch has nothing to do with HSC - I took clutch switch out - it was a little dirty - but not terrible - sprayed everything with contact cleaner - put it all back together - (seems like a very flimsy way of keeping a switch in place) - and now everything seems to work as it should - so HSC working when in first gear with clutch held in as well as in neutral!
