heavier springs front and rear. Check the Race Tech site, or talk to Ryan at Eibach, he is a TT member. I bought heavier springs but dont have them installed yet. I didnt go as heavy as Race Tech recommended, just because I didnt think I wanted the drastic change and I wasnt bottoming mine much. I go about 275 and my best buddy goes about 315-320, so we know how it is. I hope hoping to get mine installed soon, I will let you know how it feels. :applause:

My 17 yr old son goes 265 and 6'2 with his yz450 and having NO fear yet the heavyest thing we found was a 6.6 and that is still not enough!We went to the bigest fork springs as well ,along with heavier and more oil in the forks.

After this he still bottoms on the big stuff.So at 300 plus I bet you need a stiffer set up.Let us know what you end up with!

Call Randall at Pro Works Racing. The are an established Race Shop that maintain Team Maesto Suzuki's bikes. They did my bike and it was incredible the difference it made. I had mine set for a 240 lb rider.

If you take the stuff off and ship it to them they will ask you the type of riding you do and you weight and the they will get it in the ballpark. After you get it back it is easy to fine tune.

They have some very talented riders riding with their stuff and I guarantee that they will be a BIG name soon. He works alot on Motocross bikes and is really interested in Off-Raod stuff(Enduro's/Hairscrambles)

Don't just get heavier springs, get your suspension properly serviced and revalved as well. It is the best money you can spend. It doesn't cost that much to do anyway.

The front forks are valved very soft and when you weigh a little more than the 75kgs that they are designed for like we do, this causes all sorts of problems. Heavier springs can't compensate for soft valving. I found out the hard way.

I just got heavier springs, .50kg/mm front, 6kg/mm rear, and although there was a huge improvement and the bike sat up in its stroke, it was very hard to get the compression / rebound settings right. I had to add a bit of heavier oil to the forks, it worked a bit, but still crap.

I have a riding mate that had his suspension set up properly by a tuner and when I went for a ride, OMG!!! What an improvement. I thought mine was set up pretty good, not even close.

I have bitten the bullet and after a quick call around of a few suspension shops, my suspension is off my bike and making it's way to get worked on.

For all you Aussies, MPE suspension in QLD, $290 all up for full service and revalve front and back! Cheap!

As Matty05 says:

Ditto. Forget about just spring changes the valving and adjustments wont work for big boy springs. Send the forks and rear shock out to the pros of your choice! Best money mod you can do! :applause:

How hard is it to install the heavier springs front and back?

It's about a 2.5 wrench job on the scale of difficulty, 5 being the hardest. The rear is a no brainer, but the front is a little trickier. Just follow the manual, and you'll have no issues. I did my forks a month and a half ago, changed the springs, oil and reset the level and what a difference!...SC

I just took suspension off and sent it away on monday.

I took the forks off the bike, undone the top caps and emptied out all the oil I could.

I did the caps up again and wraped them with bubble wrap. I emptied oil to save on freight costs.

With the shock, I just took it off, gave it a scrub to clean it and wraped it up with bubble wrap.

I sent them by air freight. I live in a very isolated place, freight costs a lot. I would have just post them but it would take about 3 weeks to get there as opposed to 2-3 days. I ain't going to be off my bike for 2 freakin months!

If I were you, I would make up a wooden box, take your suspension off, wrap them in anything like bed sheets, rags, towels, newspaper. put them in the box and send them away. Don't worry about tipping any oil out, just box and freight. It won't cost much for you over there for freight at all. The forks weigh about 4kgs each and shock weighs about 4 1/2 kgs.

It was way cheaper for me to send them seperately. 5kg freight bags cost me $30 each. I sent mine and my girls suspension away for $180. They would have charged me about $260 if I sent it all wrapped up together. It would have cost me about $50 to send it by post.

to do your forks properly and change the oil it takes longer......

to just change your springs it takes about 2 minutes each side!

Take them off of the bike and send in the two forks with nothing on them. Take off the tire and slide them out of the triple clamp. Remove all of the guards and calipre equipment. It will be the forks only. Go buy a box from a packing store and wrap them up in a blanket/sheet.bubble wrap. I would do the rear seperatly.

A $20lb package that is 54"x8"x8" from LA to Houston is approximately $25 to ship. That is if you package it yourself and drop it off at a UPS store.

I am not sure on time/turn around to get them done I cannot imagine it being over a week. Pro Works is busy but they are always working on them.

I told them my weight and that I ride Enduro/Trails and they knew what to do. They had to replace my rear spring, because I am a fat ass and when I picked it up they set the sag.WHOOAAAA! :ride:

I did not realize the difference a suspension makes. I think that the next bike I buy I will not even start it. It will go directly to Randle and Pro Works. He has brand new bikes in there all of the time. As far as I am concerned it will be the first mod I make on any bike from now on. :applause:

a cheap plastic 2 gun case(about $25)works great and has just enough room for compressed forks(no springs or oil) and shock (no spring) wrap them in newspaper in case they do move around(but the eggcrate foam holds them pretty good)the ups store will make a box for it for under $10 and its about $20 to ship its the safest,easiest way and its reusable,just make sure the place sends it back the way they got it :applause:

Me neither!

I had always read and been told that suspension set up best ever thing you could ever do to your bike. I was even sold on this my self. But I was more interested in spending my money on a flash pipe!

Never again! I can't wait till I get my suspension back. I had put up with it for too long. I also swear that suspension will be the first mod I make on any new bike.

I was once told "The best suspension is the best you've ridden" how true. I have been shown the light!
