Anybody have any ideas ?

Just don't lower it too far or it'll look kinda silly.

You may want to contact a suspension specialist to get it professionally lowered. It may be less expensive than you think. That way your handling isn't comprised with a half-a$$'d solution. I'd recommend calling Factory Connection for some input or someone local if they have a decent rep...

Just lowered a spare pair of forks and shock for my girlfriend so she can ride my 450mxc comfortably. It involves having a spacer machined for the front forks and shorter springs for the proper wieght and you will only need an internal spacer for the rear shock which will involve disassembling the shock and installing. I have the blue prints I can fax you if you're going to take on the project yourself.

Yeah, you put smaller wheels/tires on them and they look . . .

I believe you should be able to get about 3" lower before running into problems by modifying the forks and shock. Any good local suspension tuner should be able to help.

Another trick is to cut down your seat foam or buy a "short" seat. Some folks have also cut down the rear subframe...

Good luck.

I've always had my dirt bikes professionally lowered (I'm 5'1") when getting the suspension revalved. In my opinion, the only proper way to lower a bike is via both front and rear suspension mods. Don't do the Kouba links, don't slide the forks up or down in the triple clamps, don't back off the sag, and don't solely rely on cutting down the subframe. And if it's a KTM, I wouldn't recommend cutting the already-dismal seat foam. I also wouldn't go more than 2" on the suspension if you plan on riding any real trails on it.

I decided not to send my suspension out on my KTM 450 EXC, as it's working pretty well as is, so I went with a lowering kit from RaceTech. It was about $200 (including a bladder kit to replace the piston in the shock reservoir) and is fairly easy to install if you are used to tearing apart your forks and shock. It has spacers for the shock and top-out springs for the forks. There was no discernible difference in the handling, other than the benefits of being lower to the ground, and it still feels well-balanced.

I have a Guts Comfort Seat (best money I've ever spent on an after-market product...hands down) for dual-sport stuff and non-technical terrain, but am grudgingly considering cutting the stock seat down for the gnarly stuff. I'll just hafta get a better pair of bicycle shorts, I guess...

I bought my 450 EXC off a guy who modified the subframe to lower the bike one inch. I tore it off, being closer to 6', it was hard on my knees. Might work for you, it's fairly straight forward and easy modification to make.

That's a poor idea. You should be lowering it as little as absolutely needed to enable you to ride it. Otherwise you will be screwing up one of the best off-road bikes made.

I don't know you, so don't know how much dirt riding experience you have. So at the risk of telling you what an experienced rider would already know, you DO NOT "need" to flat-foot a dirt bike on both sides at once. (In fact, if you can, it probably means the bike is set up too small for you.)

There are lots of good, short riders who can't even flat-foot ONE side when they are centered on the seat (they slide their butt towards whichever side they want to put a foot down).

Even on my road bike (DL-1000) I hardly ever put both feet down at once (usually, only when a passenger is getting on or off). On my dirt bikes, I hardly ever put a heel down, even though I can get one down if I need to (on my kick bike, I put the left heel down when kicking with the right foot, that's about the only time, other than dismounting).

IMHO if you are trying to lower it enough to flat foot it both sides, then you either shouldn't be riding that bike off-road, or need to develope increased riding skill. (I don't know if you really want to lower it that far, but you did say "as far as possible".)

I think depending on the rider lowering can be the best mod for a bike. I RC's bike is lowered. If it is good enough for the best ever it is good enough for you too! If you tip over all the time and do not feel confident at all you need to get your feet on the ground.

The seat is free and easy to do. I didn't even ride my new 300 before I cut about 2" out of the seat foam. I don't sit very much at all on my dirtbike so I could care less about a squishy seat.

Any suspension place can lower your bike for you with a service. It doesn't cost much at all. I make an external spacer for the rear shock for the linkless KTMs. You can install it yourself if you are into working on suspension. It goes between the sealhead and the outer C clip. It pushes the sealhead in the distance of the spacer. This works out to be the same as an internal one. To do it you need to release the Nitrogen pressure from the shock.

If you lower the back very much you need to lower the front to match or you get some pretty weird handling. You need to put spacers in the cartridge to prevent full extension. You also need some shorter springs to do it right. Those are a custom item.
