DR650 suspension upgrades. Who, Where and how much?
« on: June 12, 2014, 06:44:33 am »
I seriously need to upgrade my DRís suspension. In the long run it will be cheaper than replacing the bits that are breaking and falling off when I take it off road. At the moment I am looking at about R7000 for stiffer springs, cartridge emulators for the front and a revalve kit for the rear, all from Racetech in the USA. Are there cheaper options available? I would prefer to shop locally and I donít want to do springs only. Also prefer straight rate springs to progresssives.

If you're serious about riding the 650 as an Enduro type bike maybe go for a DRZ front end. A "straight" swop unless you regard making fittings for instruments, lights and loosing your ignition lock not as "straight".

RaceTech emulators work well if fitted and adjusted correctly.
What spring rate are you looking for in the front?

In the rear shock I'd just get it revalved. You need a bit more low speed compression, else it's fine and it's a good quality shock. if you're fat you might need a stiffer spring too matched maybe with a tad more rebound damping.

According to the Race Tech Website, I need  .7kg/mm springs in front   and an 8kg/mm at the rear, up from .4 and 6.5 respectively

The first thing I used to do with a new enduro bike was fiddle with the suspension. As an inveterate Scotsman I figured that if you weren't bottoming your suspension at least once a ride you weren't getting your money's worth! Also the suspension linkages usually came dry from the factory, like the headstock bearings on my new DR.

However, when I picked my my shiny new DR it felt just about right. It is a bit spongy but that's because it is carrying a big bike. It has never frightened me or stepped out of line so I have left it be.

Lecap is quite correct. The DRZ suspension is just light years ahead. I would consider tackling an enduro on a DRZ if I was 30 years younger. In fact the DRZ is just a better bike full stop if you want to do some serious attacking style riding and you may be better off considering one with all of it's attendant motor hangups if that is your bent.

With my weight, the suspension is completely overwhelmed. Over the rough farm roads where I usually ride it bottoms out and does not react fast enough, so I hit the next bump while it is still compressed and the bike is all over the place and bits start breaking off. My knees really take a hammering because I have to stand all the way.

Problem is Iím spoiled. The suspension of my 990 has been completely reworked and it just sails through the same stuff without even noticing.

The quoted OEM front and rear spring rates are incorrect.
I doubt anyone will be happy with a 7N/mm linear spring in a DR650SE front end.

Something between 4.8 and 5.5N/mm will likely work well in the front. It will be a bit harsh but that won't be avoidable with linear springs.
You have to be more than heavy boned to justify a 80N rear spring.

I contacted Ken at Game Services. I'd rather have him sort it out than spend a lot of money importing some stuff that in the end may not be required or don't suit my needs.

Have to agree... 7N/mm is way too high. I might have some springs (good 2nd hand and new) with the correct rate in stock - just send me a PM if interested.
