Rear pre-load suspension

[Ebrahim]

Hi all riders

I want to readjust (stiff) standard factory rear pre-load suspension for dual riding on GT650R, the owner. Manual does not suggest how many notches to turned the clockwise direction. Any idea?

It really is just adjust it until it feels right, suspension is a personal thing when it feels right for you then that’s it, I would move it up 2 notches & see.

I recently adjusted the suspension on my GV650. I moved it 2 notches and next ride out I knew at the first pothole that I’d overdone it. But I think by moving it a couple of notches the difference was probably easier to notice.

Hi Guys

Thanks for your reply I am happy with factory setting on solo riding, what I liked to know is the recommended manufacturer setting for a pillion passenger, I tried with a passenger on standard-setting with rear spring sank too deep so that I readjusted both mirrors and the front tyre was wobbling out of control on the corners a bit dangerous, I guess I will try two notches down if the mirror view did not change with pillion then it should be ok.

I doubt that they will recommend a setting because there can be such a big difference in people, are we considering 8 or 18 stone. As a rider are you experienced at carrying a passenger, plus is the passenger an experienced pillion rider, if not you might be fighting them for control of the bike and if they are heavier than you they might be making the bike do things you are not expecting.

Hi

I have no experience riding with a pillion, pillion has no experience as a rear rider. I am 92 KG and my pillion is 91 kg, that is why it is better to get the correct pre-load compression, looking at D Moss videos and others on u tube if rear-seat plunge too much front fork and front tyre loose grip then front wheel starts to get out of control on corners.

I still doubt that there is a recommended setting, if your gt is like my gv there are only 5 settings and mine was on 2 to start with so only had 3 options.(I am 90 kg). Follow the first advice and put it up 2 notches to start with.

My advice would be take your pillion out for a lot of low speed urban riding with lots of corners, roundabouts, lights plus especially practice stopping, starting and pulling away. There is a big difference in both handling and performance between solo and two up.

HI

Yes, I agree dual riding is a new experience requires slow practice for safety. My GT must be different with yours in a way that mine does not have any notch or click it is a cylinder with threats. For adjustment of pre-load, it requires one full turn to count as 1 turn. I will measure the static sink, loaded sink it is recommended that 30 mm loaded sink is about an average acceptable for a single rider. I take it from there.

Hi

Following my last topic, I bought C spanner for my GT 650 R rear preload adjustment the diameter of spanner was short but the handle was big enough to move around. I bought another adjustable C spanner 51mm-121 mm its handle is too big to move around the spring it touched rear tyre. Any idea of how I can turn the adjuster to change pre-load.

[Andy650]

 

AS you are trying a C spanner does the adjustment on your suspension consist of a series of holes, which are just under 6 mm diameter around the bottom part of the unit?

Oops, posted twice.
