ASC

[Stevie73]

Might be a daft question this....

how does the ASC work on a 12GSA? And what would the effects be of riding on muddy lanes with it not turned off I think I might aready have the answer to that....

You gets lots of coughing and popping and not much forward motion as the ignition cuts in and out.

So basically, once the bike senses the back wheel spinning, it dumps the power? If you're riding through thick mud, and trying to keep your throttle open and steady, would this not then load all the weight onto the front wheel and de-stabilise the bike?

I'm asking, because it's what I experienced whilst green laning a couple of weeks back. Whenever I was in the mud, the back end just kept coming round when I felt I was loosing it. As I felt the bike de-stabilise and the back coming round, I'd open the throttle to try and straighten it up, but she just span out every time!! Was a horrible feeling, cos I just felt like I had NO control in the mud

I had the impression ASC was mainly for use on-road and it can be switched off when in the sticky stuff? I am looking at a GSA with ASC so it would be good to know for sure.

I think the ASC is mainly for road use but it does have a "sport " mode which IIRC lessens the sensitivity of the ASC

Can see the validity for road riding definately. There is a less sensititve setting for it, but for off road sticky stuff, I'll be turning it off completely in future. I reckon it actually makes the bike unpredictable and dangerous off road if you don't turn it off. If the bike just decides to dump power, when you're trying to keep it nailed on to get through the terrain, then it's dangerous for sure.

I just wonder how much power it releases when it senses the back wheel spinning? And if it could really, de-stabilise the bike...?

The effect is similar to running out of fuel or running on one cylinder. I guess it must retard the ignition briefly.

I'm not sure about "dangerous" - I've experimented with the different settings on gravel tracks - if there isn't much grip it is predictable in that it starts to work - I guess if you are counter steering to cater for the rear stepping out and then it stops stepping out so much, it might be classed as de-stabilising the bike by catching you out

make sure you turn the ABS off as well - somewhere on this site there used to be a video of someone trying to control a steep offroad downhill descent by sliding the back wheel, the ABS kicks in and he ends up being unable to stop until he got to bottom - bounced around a lot on the ruts and lost his top box in the process.

i understand all if that so far... can someone quickly explain the 'benefits' of the Asc system. I have ASC installed and I only notice a judder through the rear foot brake pedal when braking hard, and the wheel spin difficulties on muddy surfaces, lots of smoke and warning lights...

Benefits are....?

... your dignity, skin&bones and an intact bike.

Try powering away at traffic lights on a wet and icy morning over manhole covers you didn't spot... you'll soon find out the benefits of ASC!
