How hard does your front end dive

Ive noticed when i come to a stop my front end seems to dive, and i dont know if this is normal or not. I havent been able to adjust the suspension for my weight yet being that im about 40lbs heavier than the previous owner, but i was just curious if this was normal.

I weigh about 180lbs and am 6 feet tall. I may just need to adjust it bc the fork seals should be fine with only 10k on them

Re: How hard does your front end dive

the fork seals have no affect on front end dive. they just hold in the fork oil.

your front is gonna dive under braking all the time because yours and the bike's weight are shifting forward. put a zip tie on the fork tube up against the rubber dust cap. go out and brake a few times just as you normally would then look at how much the zip tie moved. if its not completely at the bottom you're fine. but if its close to or at the bottom and you aren't braking really really hard then the suspension is too soft. stabbing at the brakes rather than progressively squeezing them will also make the front dive harder.

if you can't convince them, confuse them.

How much of a dive are you talking? I'm a big dude and my front end doesn't really dive unless I really get into the front brakes or liftin the rear wheel off the ground

Re: How hard does your front end dive

What do you mean by dive?

The front forks should compress to a certain rate as the weight is being shifted onto the front but the rear wheel should not lift unless your braking quite sharply and shedding a lot of speed.

Do what CBR929RE said...

Twin, I think by dive he is thinkin that his forks are compressing more than usual.

Re: How hard does your front end dive

Ah I understand.

Maybe the previous owner had set them to a softer setting for touring or going over a lot of bumps and forgot to put them back?

Re: How hard does your front end dive

You could add preload or compression damping to slow the rate.

Re: How hard does your front end dive

How many lines are showing on your front fork spring rate adjustment. At your wieght I would say you should be showing 2-3 lines. That should set your spring rate (Also called sag). From there if it still dives on you twist the compression adjuster at the bottom of your fork about a qaurter turn at a time clockwise and then try it after each adjustment. If you have the owners manual it will give you the the stock set-up specs and tell you how to reset them back to stock if you want to start from scratch.

Edit: Or you could spend around $40 to have a shop set it for you.

I'm 6' and outweigh you by 20 lbs., and for "street" riding, the stock suspension does a decent job - once you set it up.

I'm curious - your earlier post said you haven't been able to adjust the suspension..

It sounds like you're a bit unclear about what's adjustable and what should be adjusted. The front suspension has three adjustments available: Preload, compression, and damping (or rebound).

Preload affects how much pre-tension is placed on the springs.

Compression regulates how quickly the fork compresses.

Damping (or rebound) affects how quickly the spring rebounds (uncompresses) to it's original length (with the preload applied).

On the 954, the damper adjustment is the small slotted screw on top of the forks. The preload adjuster is the larger nut on top of the fork. Compression adjustment is handled by the small screw at the bottom of the fork.

You need to setup your suspension to factory levels, then tune them to suit your ride.. It's as much a how-does-it-feel-to-you, as each rider's individual needs are different. Given your height and weight, you'll need a tad more preload than factory, but not much. The other settings all depend on how you ride.

Factory settings are:

Preload - 7 turns from full soft
Damper - 2 turns from full hard
Compression - 2 turns from full hard

Re: How hard does your front end dive

Dont know if your a new rider or what but a quick question are you balancing the bike by using your rear brake aswell? If it is setup your strugglin with I feel your pain but my problem is the other end off the scale im about 5.8 with me boots on an weigh 70 kgs..only thing u can do is set it stock then work one click at a time keep a book on the adjustments and test ride each change.make sure u use the same roads for the changes that way u get an idea for what is workn best.

The front brake is gonna cause ur bike to dive the most SLEEPY. the back will cause the same on a lesser level.
