The DR650SE’s are noted to soft and under damped components for all but the lightest riders. Old non-adjustable damping rod type and a compression damping and spring only adjustable rear keeps the DR650 off-road in check. Fear not! are some pretty cool for the stock DR suspension. One of them, of would be to take the components to one of the performance suspension experts do this type of work.

You can buy the parts and DIY!

While the option is to upgrade both the and dampers both front and if you are on a budget try replacing the springs and rear with ones for body weight and riding and putting in some nice 10 weight suspension oil.

Kouba has a has a nice write up on how to change a spring on the DR650.

Forks and clamps from other Edit

Some decide to the stock 43mm forks better ones from motorcycles. Some of these also have heavier than the stock .400 springs and may not need new springs. up are late model forks will also require the clamps as they are a different stancheon, or inverted.

This upgrade can be done at a net $0 if you take your time on parts, the stock forks/wheel sell for what you paid for DRZ forks/wheel. The spring rate for the and the DRZ400S is 0.44 kg/mm, the E has better damping though. I the DRZ forks because they are for higher weight bike PM me on the ADVRIDER forum if you want the pics. I’ve been my upgrade now for about 1.5 years and very happy.

Also the DRZ rear shock upgrade.

forks from other Edit

An even easier is to find 43mm forks other bikes that slide straight into DR650 triple clamps. bikes with 43mm include the XR600, DR350, model RM125 and RM250, and to 1988 CR125 CR250 models. The conventional forks the 1983 to 1988 RM125 and options are the easiest, as with a bit of you can keep your stock wheel, disc and speedo in place. These will straight into your triple clamps.

They are a longer fork, but you can them down into the to get closer to the original setup. front wheel, axle and drive will all fit perfectly. you will need to make a adapter plate to position caliper correctly for the 290mm of the DR650. Otherwise, you will the orginal RM125 or RM250 wheel and settle for the 250mm

The spring rate for the RM125 is usually around 0.33 and the RM250 springs are 0.35 so you will definitely want to fit springs.

Modifying the existing forks Edit

The most cheapest mods? Replace the 5w oil with 10w for stronger damping. riders have experimented 15w, some report results while others say the will shudder on fast Others have also their fork oil for a 12.5w as a The forks should compress 25-30% of their travel you sit on the bike; many riders they sag more than so add preload to the forks.

You can remove the very heavy steel preload spacers on top of the and replace with PVC tubing. with the length of this, riders report that these a half inch than the stock ones well. Heavier riders can ramp up the preload on the rear to get the right amount of sag.

note, increasing preload not increase your spring it only achieves the right of sag!

If you are on a strict budget, a option is to cut and reduce the length of springs by 10% which will the spring rate to 0.44 and make your preload correspondingly longer. Read about this here. budget option that is is increasing the level of your oil; this reduces the of air in your forks so on compression makes your forks so acts in a similar way to stronger (although at a different rate).

argue against this due to the strain on fork seals. more about this .

Your next option is to at stronger springs which very expensive so well looking at. Racetech have a calculator here for working out the rate to suit your and riding. For better damping rebound damping) look at either emulators or intiminators.

are slightly cheaper, but need the dismantled and are more work to Read more here .

rear shock mods

For the vast majority of riders the shock is underdamped and undersprung. are your options, working the cheapest to the most expensive / intensive.

The most basic mod is the highest damping setting and the preload on the spring — as per the The rear shock should around 25-30% of its travel you sit on the bike. Of course this not make the suspension any stiffer, but at it should correct the excessive sag for most riders.

The next mod be to remove the rear shock, and the 5w rear shock oil and replace 10w rear shock oil. thread has lots of information on mod. This will increased damping and lessen the stick effect of the stock It should cost around $20 for oil and the again for recharging the shock nitrogen.

Please note, the stock has insufficient rebound damping so you may to work out a compromise e.g. go up to a 15w oil and have harsh compression but at least some rebound

The next mod costs more, and the above but includes a stiffer spring. Racetech have a calculator here for working out the rate to suit your and riding. However, once you the money on a rear spring $10 to $150) it makes sense to the stock spring and not bother trying to make the stock work.

Click here to see instructions on installing a Gold setup (about $170).

also has a replacement shock kit is very easy to install and with a beefed up shaft and Tech Gold Valve. You get a new spring setup for your and riding style.

Next If you don’t feel like it all yourself, suspension specialists rebuild your shock for you a better spring, revalving, and recoating of the shaft etc.

The most expensive mod is to buy a complete rear shock like the or the Cogent. There are also a DR650 rear shocks the United Kingdom that can be via Ebay, such as the Hagon and It’s likely you will get what you pay for, so do your first if considering a cheap shock.

If you like messing you can adapt shocks from bikes to suit the DR650SE, the common seems to be the DRZ400 shock which has better with rebound and compression but you’ll definitely need a rear spring — the one is even softer than the DR.
