    I'm running the .47's and with 5mm of preload, they're nicely in the static/race sag ballpark according to Neduro's book.


    Have you tried the stock springs + Intiminators?

    Hey guys, I have been trying to figure out what to do about my forks and just read through this thread. My bike has supermoto wheels and I only ride street. The biggest reason i want to upgrade my front forks is brake dive. It was bad with the stock brakes but now with the 320mm front rotor, it can only get worse. I am pretty sure I am going to go with the intiminators, but what springs should I get? I am 200lbs, never carry any gear, and only ride street. i was thinking .50 straight rate springs to go with the intiminators. Or should I get the procycle progressive springs along with the the intiminators?

    I believe the intiminator site specifically says NO to progressive rate springs

    stock springs are progressive and many use those just fine.

    yes opinions are all over the place.
    difference may lie in the fact some use dr on the street and thus like it stiffer and some in the dirt plusher. stock is .40 and i'm 175lbs and the .50 is to stiff for me. i ride alot of dirt and want it plusher there but still like how the nators keep the front end from diving during braking on the street. setup is always a compromise somewhere. if i rode offroad all the time i'd use emulators, but i ride aggressively 50/50.

    I think I will go with the intiminators and .50 straight rate springs.

    Should work very well. For road riding, you may want to go with a 7.5w oil to slow the rebound with the heavier springs but that's about it.

    Taking out a 0.020" shim and replacing it with a pair of 0.010" ones would also make the Intiminators feel slightly more like Emulators.

    When testing my TT350 with the Triumph Scrambler Intiminators, I rode them straight for a while, no dive at all, no movement at all unless you rode up a kerb. Then with a 0.020" shim removed which made them feel remarkably like stock with the amount of dive. I ended up with the 0.020" out and an 0.010" in. A little more brake dive than the DR setup but far less than stock and still very supple over the rough stuff. The preload spacer was just over twice the thickness of the Intiminators and I've removed it completely.

    I'm the same weight, SM setup, 100% street ridden and I accomplished what you are trying to achieve...reduced brake dive by talking to Pro Cycle and taking their advise. Eibach .47 kg straight rate springs and intiminators and 5W oil as recommended. With the improved braking from the galfer SS brake hose(s) I don't feel like I need the bigger brakes for my use...I don't race or do track days. I went to a 7.5 rear spring too. Bike handles well for my purposes. Progressive springs provide a softer first few inches of travel...that's what you need to get rid of. Call Pro Cycle tell them your setup and what you want to do and see what they say.

    Been too busy with work and young kids to install myself, so I just had a service center install a set of Ricor Intiminators and a Ricor Rear Shock on my DR650. 2 hours labor on the front forks, 1 hour on the back shock at $85/hour. YMMV.

    Sure, I could have done it myself, but it wasn't worth waiting for the free time to magically appear nor the spousal malcontent.

    Well, i chose to go i small increments, 1/4 turn did the trick, thanks for encouraging me to adjust, i knew they could be adjusted but just needed a nudge to get off my but and do it, worked like a charm.

    Sorry to unearth this, but was looking for some advice. I do 98% street (cit/highway mix) on my DR650 and was planning on getting Ricor shock and Intiminator combo. I weigh 190 pounds. I have pretty much decided on upgrading the stock front progressive springs (.38 to .53), but I can't decide on which.

    From all my studying on this issue, it seemed like a .47 linear spring was the way to go. I spoke to Brian at Ricor and he recommended a .60, which threw my understanding into a loop. I'm confused at this point. To make it even more confusing, there are quite a few people that found the Pro-Cycle progressive springs (.45-62) to work well also. Thank you in advance.

    While no expert on this topic, I think the discrepancies that you are finding are based on riding style.

    IF you are pushing your machine, riding it hard in dirt for example, you will want a stiffer suspension. If as you say, you are mostly a more casual street rider, then the slightly softer springs will be more comfortable and/or appropriate. I have found that the "Racetech" suspension recommendations will give you a stiff - potentially harsh - ride on the street, but put that same setup onto a technical trail it can be quite helpful.

    Suspensions are in the same category as Carburetor setup. It's part voodoo and part subjective personal preference and part primary use and ALL compromise.

    YMMV

    Give Jesse at Kientech a call, he's very knowledgeable on setting up the suspension on the DR. 541-472-0835

    I called. He said he recommends .48 with the Intiminators for my weight. He also doesn't recommend progressive springs.

    Same thing told me on springs, I took his recommendation on straight rate springs and have been very happy with the set up. I had him rebuild my rear shock as well and between front springs with Intiminators and rear suspension it transformed the bike

    Do you ride more street or dirt? Thanks by the way.
