*CLONK* from forks - SV650.org

03-07-10, 07:51 AM

I've had the bike just over a year and, being a relative newbie, I wasn't aware that the clonking sound my forks make was something to perhaps be concerned about!

Anyway, I took it in for the MOT and the chap said that my forks shouldn't clonk, but that it was probably OK because a lot of SVs do it. I must say, I've been riding the bike for a year and the clonk hasn't got any worse. I get a clonk when I compress the forks hard - e.g. when I use the front brake to come to a halt a bit sharpish, or when I go over a pothole. I also feel a "clonk" in my hands at the same time (i.e. referred to the handlebars from somewhere in the forks).

What could this be, is it something to worry about and how can I fix it?

"they all do that Sir, it's a design feature"

at least, most do and if it isn't getting any worse then I wouldn't worry about it.

Lol! I like the way manufacturers use the words "design feature" ...

I'm not so worried about it, I took the thing to a Suzuki main dealer for the MOT and service (surprisingly, cheaper than any private, local bike mechanics!).

I have the same problem with mine. I have been told that it is my brake calipers and discs. Been told it isnt a problem.

the clonk is from loading the front up quicker than it can handle. Happens normally under heavy braking or when hitting a bump.

Nothing to be concerned about unless it get worse, then its a case of overhauling or swapping

as far as i understand it, its something to do with the damper rods hitting the oil or something along those lines .... i think

It's normal , when I fitted hagon fork springs "clonk" went and front felt a lot better
But as already mentioned nothing to worry about but would recommend firming up front unless you are a slim jim

I had a "clonk" every now and then when going over a pot hole etc.
That is until i had my headstock adjusted as part of a service 4 weeks ago, havent heard it since.

SV clonks, never heard another bike do it yet.

Mine does it as well, spent ages looking for the cause, but found nowt. Rides and handles OK, asked at the MOT they found no probs. Just carry on
