My DR currently has a MPE set up in it from the PO and he tells me its set up for a light weight fella 110kgs
Im slightly bigger
lets round it and say 130kgs :SWhat rear spring would you recommend for me, thinking that I will be doing a big ride in 2015 so will have a good load on the back as well
I have no idea what has been done to the front but im guess it should be ok for now
My DRZ 400e also has MPE from the PO but has a Teknik 6.6 rear spring are you able to confirm what this is rated to for me

Many Many Thanks

6.6 is about stock, you sure thats right? Our general rule is 8.0 for under 90kg. 9.0 for 95-120kg and 10.0 for 120kg plus.
That’s rider weight only, it accounts for 20-30kg subframe snapping gear.December 6, 2013 at 9:55 am #252293thas ok I f i really was in a hurry i could of picked up the phone lol
I just rechecked and it is a 6.6 spring so I guess I best repalce that one as well or my fat ass will break it hehe
So my next question would be, how much for a 10.0 spring for a DR and DRZ

How hard are they to remove….I have done springs in a car before with a mate and i havent died from doing that yet.
Im not sure how long ago the suspension was done so my guess is it may be better to send the hole shock assembly down to get it looked at…..gezz how much would that be.
thanks in advance

You won’t break the 6.6, just squash it when you sit on it.
If the 6.6 is in the 400, that’s more like it, still a bit light for you but not too bad. 7.2 would be better. see how it feels.If you are REALLY 130kg id use the 10kg in the 650. It’s a fkn big spring for the DR and I really only use it for the biggest heffalumps. Either spring is arrr $150 OB price.
Hard to know what’s in the shock, BUT i do run the rebound dampening WAY harder for these big springs to prevent PDS (pilot discharge system) type crashes when the stored energy in the spring tried to launch you into sub orbit.Shock rebuild/revalve $220 plus seal/bumpstop/parts if required. DR650’s are pretty good, nothing much goes wrong.

The 650 and 400 shock is totally different, can’t swapDecember 7, 2013 at 3:25 am #252303Teknik wrote:That’s one of my 9.0kg springs. It will be OK for you, just a little light.
