Front Fork Springs.

mike · Clubman A

Hi John

unless the fork springs have been upgraded from standard they should be about right or a little soft for your weight. Don't forget that your riding kit etc will weigh a lot.

Before you change the springs the first thing I would do is look at the oil height in your forks. The range for most forks is about 90 to 120 mm of air gap. If its close to 90 I would drop it down to 120 (check your manual for min and max oil height). Set your rebound and compression clickers to standard.

Second thing would be to check the rebound damping. Start at the standard setting and increase a couple of clicks at a time until you get a feel that suits you. In my experience harshness is just as easily attributable to the rebound setting as the compression.

Third thing- work steadily through the compression clickers a couple of clicks at a time until you get the right feel.

Don't just assume that its the front forks that are causing the harshness- the rear shock settings can have a very similar effect.

There is a spring rating / rider weight checker on the net (racetech I think or something like that) - have a look there. Perversley too soft a spring can feel harsh if you are having to up the damping to stop bottoming.

Thanks Mike

I will have a look at the settings. The bike felt very uneasy on the front, and feels like its going to let go at any time.

Do you have any thoughts on front tyre choice?

Cheers John.

What's wrong with the ac10 fronts?

Jeff · Clubman B

just my opinion, but put a new one on because they are very well priced , and fell off numerous times in 2 outings, which all caught me by surprise .with all motorcycling you need to have confidence in the front tyre. ... Im not a enduro rider and not trying to start a tyre debate. but will not be fitting another one, if your after tyre life/high milage this is probably the tyre for you. its the same with anything i suppose you get what you pay for, My preference is Mitas C19 £45 from CMS exeter.

Says it all really

Hard tyres last longer and grip less

Tried an AC10 once but found it too hard and inflexible so I gave it away with 2/3 of the tread on it

A soft compound tyre lasts me about 3,000 miles and grips well. Something with less grip that lasts longer is next to useless.
