Big guy on an sm

Recommended Posts

Hey guys, as you can see i new here on the board and im already hooked!

Anyways I wanna buy an 09 drz400sm next week. I have done a lot of research and here in hawaii i think it would be the perfect bike. The only problem is I always see much smaller people riding them.

I am 6'2'' and about 230lbs. My question is what if any suspension mods would/should I do to the bike. the dealer says tightening the coils would probably be good enough but I figured you guys would know better.

I plan on using the motorcycle to get all over the island of oahu and play around in general.

I plan on eventually doing the 440 big bore kit and all associated mods to get get full power from it but not for a while.

tell me your thoughts.

thanks, will

Will,

I'm in the same boat as you approximately. I find that the with stock setting the bike wallows a little and is a little squirrely at speed. For your size you will need to re-spring to a higher rate front and back. I'm planning on doing it to mine this year. I think racetech makes the springs. in the interim though you could adjust the preload by 1/4 inch and then tighten up the dampening a bit. Wouldn't be perfect but it would help and it's free!

Thanks for the quick reply n-f-g. Im pretty sure I could handle the rear spring change my self but I have never taken apart the fronts before. Is there a chart or basic formula for the appropriate spring rate to choose?

thanks again and keep it coming!

will

google racetech,they have a spring chart for that.

the fronts are just as easy as the rear if not more so.

unscrew top cap,remove old,install new and screw cap back on.

You will want to revalve at the same time and consult a knowledgeable suspension guy for shim stack and oil weight. I am a lot bigger than you so mine was extreme. I used MX-Tech as they are close, gave me a great deal and had the right springs for my weight.

I'm 5'11 and 250lbs and mine feels great. That being said I bought my z used.

But the probability of the old owner weighing the same as me is at least 1000 to 1.

I say buy it ride it and then start your changes. Your going to have fun it's lakine.....

Thanks for the replies!

I am definately buying the bike this week.

Im gonna ride it as is for now and see what it feels like. I was hoping the fronts could stay stock.

Are there any TT member in Hawaii that know a good shop?

thanks, will

Just rode mine after suspension mods today...Stiffer fork springs, racetech 6.0kg rear spring, and new Avon Distanzia's 150-70/17r......bike is taller, geared higher(because of the tall rear tire) and rides firm-no wallowing AWESOME!! I'm in love again. Good Luck and YOU SUCK (for living in Hawaii):banana:

      Hey all, 
      I'm looking at buying a 2004 Suzuki DRZ400EK or at least I think it's an EK according to Vin lookup websites, but it does not appear to have a kickstarter. I was told the bike was owned by a motorcycle dealer and that it has a current green sticker, and a California license plate but has not been registered for the streets since 2011. I want this as a dual sport but am not clear if the fact that it already has a plate means I am good to register it or if maybe they took away the ability to register it after it was plated, California loves to do that kind of stuff. Since the bike was owned by a dealer I would think they were up on the latest regulations in California, but who knows. Can anyone add any insight as to what I should look for on the bike itself like the carburetor, model numbers etc? Or do I just try my luck at the DMV?

      Hi,
      I have a 2003 DRZ (actually a KLX400) and the head tube bearings are shot.  I ordered a new set to install but I'm wondering if anyone has any recommendations on other parts I should replace while I have the front disassembled.  I was thinking about new rubber fork protectors, but are there other things that wear out on the DRZ front ends that you can only get to when disassambled?
      I also broke off a replacement key that I got for the steering lock.  I must have been made of cheap pot-metal.  Should I just remove the whole lock mechanism?
      Any tips or tricks for getting the old bearings out and the new ones in would be welcome!
      Thanks!

      Hey Guys,
      I recently bought a 2003 DRZ400S and thought it would be a good idea to check the valves clearance etc . I timed the engine on TDC with the magneto mark aligned as per the manual but I find the cam timing slightly odd. The arrows pointing upward are on the 1st and 15th pin as they should but with the magneto timing mark aligned they are not perfectly straight. Same goes for the arrows that should be parallel to the cylinder head casing. Is this normal or should they be absolutely perfect ?
