I just lowered my 954 about three inches and now is sits so low that the tire hits the undertail. I already took off the tire hugger of course. Is there an easy way to keep it from bottoming out or am I better off going back to stock? :confused:

add preload to the rear shock. it'll make it ride a bit rougher but you won't bottom it out. why did you lower it?

I am 5'11". The height of the bike was not a problem and I bought a kit that said 2" to 4" drop and it didn't seem like very much but now it seems a little more than that. I just like the lowered look but didn't want to do an extended swingarm so I thought I would try this. I don't know about the handling yet because I have only ridden a very short distance so far to prevent any further damage.

lower you go the crappier the steering gets and it throws off the bikes geometry and more important you will drag hard parts like foot pegs and exhaust cans which could cause a crash get a better link. tobefast.com makes one that is adjustable by a threaded rod and set it to a 1 inch drop and raise forks thru the tree about 1/4 to 1/2 inch that may do the trick but if it were my bike id leave it alone stock on the blade its all about handling for me...

Lowering the rear slows the steering and unweights the front wheel making front more likely to slide out, especially on corner exits since you;re on the gas and weight is naturally transferred rearward. Lowering rear also decreases swing arm angle, which increases rear squat under acceleration, further taking weight off the front. 929/954 race-bikes usually raise the rear 15 to 20mm over stock. 3" is about 75mm lower, I would not ride any curvey roads fast with a bike set up like that. BTW, i raised the rear of my 929 about 20mm and turn-in is noticeably faster. Ditto with dirtbikes: setting rear sag has a big affect on handling, stability, traction, ... You could cut the foam down on the seat to lower it a bit. Or maybe remove fab a seat pan that sits right on the sub frame plus some thin foam.

put it back to stock. if you don't have issues reaching the ground there is no reason to lower it unless you're building a drag bike or show bike..

Would lowering it up to about 15mm still have the same effect, the bike does have the facility to do this?

While the amount appears quite small in isolation, when you figure it relative to the total region of adjustment 15mm is a lot. The steering head angle is limited to a region of just a few degrees between roughly 22-25 degrees. The extremes handle very noticeably differently which is why just a few mm up or down at either end makes such a difference.
Why do you want to lower it?

Further to that, your steering is simply a matter of moving the front tyre footprint just a few mm to one side of the centre axis of the bike (or, more specifically, the centre axis of the centre of gravity) which causes the bike to want to fall inwards. The rake and trail magnify the tiny input at the bars. Altering either even slightly can have a big impact.
The entire steering process is on such a small scale as to be almost imperceptible to the rider.

I have turned it down a little, need to get feet down, Im 5 5 so now I can put one foot down safely not so much tippy toes only. Needs must but it got me wondering if that was the cause of my accident on the last blade or the simple fact I was to hot into the corner, on the other hand Im pretty sure it was after or on the apex (it was all a bit sudden to have a clear memory)

If you must lower the bike it is usually better to lower both ends by the same amount to retain the geometry. Lowering also reduces cornering clearance.

I am 6'-1" but I definitely don't have long legs, and I cannot remember the last time I had 2 feet down at the same time. I think you're a lot better off with the bike at standard height.

You've got a sport bike and you know how to ride. You don't need the landing gear down for the first 50 feet like a Harley Ferguson rider.:smilebig:

Lol, given it a little more thought the suspension was just softened more so that the bike went a litter lower when I sat on it, Im only 155 lbs

Thanks for all the input, I am going to go back to stock...Just easier that way. I love to ride and don't need anything else to jack with. I will just keep it around just in case I want to go to the dragstrip. On a different note I'm thinking about getting velocity intake stacks...thoughts?

For anyone who does feel the need to go lower, I'd recommend the Naarden Speedlink for the 954. I have one and it allows you to get pretty low as well as going higher than stock. I like the way the bike feels with the Scott's damper and rear height about 1cm over stock. The nice thing about the Naarden is that adjustment takes seconds using a Gearwrench and you can do it without any assistance.

Ride safe,
Franc

How about for me? I'm 5'00" and 110 lbs. I don't want to compromise my ride but I don't want to be leaning to one side all the time...any suggestions for a cbr600rr
