G'day Hobs,
Your fear is justified. Loose gravel can be equal to an oil patch on a wet road for potential arseovers.
I had a similar experience on the way to Jenolan Caves on a hairpin curve recently. I was not expecting such a hairpin and decided to stop and look at the curve b4 proceeding. I noticed lots of gravel spread over the road by vehicles squeezing past each other. I was way too far to the left to take the curve correctly so I decided to ride up the slope just to the right of the curve and then go very slowly backwards until I could go forward after pointing the front of the STeed roughly in the direction of the exit of the curve. However, due to the gravel on the curve the STeed started to slide backwards as well - but not so much as to go over the edge and all was ok.
After this incident, I thought about how I would handle a situation like this next time. I came to the conclusion that I should approach the gravel slowly and go as wide as possible around the curve. I would ride the clutch in first gear with enough revs to ensure no stall and not touch the front brake at all.
I would control the speed with the rear brake and clutch.
This is similar to controlling an ST around a roundabout where the 1300's fuel injector surges can also be controlled using the same technique.
The idea, on gravel, is to have maximum steering control at slow speed and to remain as upright as possible so the bike doesn't slide out from under.
Slow speed, controlled revs, right hand only concerned with controlling revs - not braking.
The same technique can b used on a gravelly T-intersection.
The technique can be practiced in a quiet parking lot by doing figure eights and seeing how small u can confidently get them. Be aware tho that overconfidence may cause errors and the STeed will fall over, as has happened to me.
The club has many more experienced riders than me tho as I have had my mc licence for almost 40 years but have only had a mc for 11 of them, so others might be able to verify this advice and perhaps add other tips as well.
BTW the best piece of advice that I heard reiterated recently was from JohnYTED who said something like "in a dangerous situation always look at where you want to go and not at the problem you're trying to avoid".
And as far as slow speed parking goes, whenever I'm in an unfamiliar location I stop in a straight line and take in the situation and then do the parking manoeuvres using the slow speed techniques described.
Hope this is of assistance.
