RT Spacer Model Number

The lower spacer from RT doesn't fit the lower collar, there is about a 3mm difference. The top spacer fits snug with the top collar. Does anyone have the model numbers of the spacers handy so I can compare the ones they sent me with the ones that work?

Top spacer which fits perfectly is model SPSC B5649.
Bottom spacer they sent which doesn't fit is model SPSC P575510.

This is for a 2014 DL560.

That's what was on the website as required spacers to go with the new shock spring. Just placed an order myself and expecting it this Monday. Got me a little worried now!

Post back here if you can figure it out! Hopefully I am just doing something dumb and it will be an easy fix.

They have been completely worthless as far as Customer Support goes, just a warning.

Yea I've already noticed with their website ordering that things are a little "different". I'll cross my fingers.

OK, so I received the spacers listed above, and although they had no markings to identify them (that I could see), they did fit correctly in combination with the stock spacers. The RaceTech spring was an Eibach, shorter than stock, but with the spacers installed they were equal in length. One RT spacer was more of a stamped metal insert, which I placed on top of the spring, and then inserted one of the stock spacers into that. (The top and bottom spacers appear to be the same.). The other RT spacer was machined aluminum, which was fit into the bottom of the spring, and then the stock spacer inserted into the machined spacer.

One thing- To exchange the springs, I clamped the shock into the vise, then used two lengths of All-Thread, with large washers and nuts top and bottom, to compress the spring. To keep it all together I snugged up a hose clamp around the top of this contraption. To compress the springs I just used a ratchet until the spring clip was accessible. Anyway, I nicked a couple spots where the threads contacted the spring. (Not sure if it's painted or powder-coated or what.). So should I worry that rust may develop on those couple of tiny spots? I figure it'll be covered in chain oil before long anyway...

Yep, directions would help. The rear spring I got from Pro Cycle was the same way, adapters took a bit to figure out since they are not marked at all. If you have some wood laying around you can make a floor jack work too. There is directions online for building a floor jack shock compressor.

I have a Harbor Freight 20 ton press in my shop, so it was really easy to compress the shock. I just took a piece of scrap 2x4 and screwed two 2x4 legs on just wide enough to catch the shock's top on the sides, looks like a square with the bottom missing. Took me longer to screw the wood together than actually removing the spring. Well worth the trouble though, I'm really happy with my spring upgrade.

Yea wish I had a nice set-up like that. Considered cobbling up some lumber for the floorjack method but thought that would take longer.

Whaddya think about how I nicked a couple spots off the powder-coat? Rust problems later, or no worries?

Yes I upgraded to Intiminators and Sonics up front, now that the whole bike will be properly sprung I can't wait to try it!

If its easy to get at put some paint on the scratches. Red nail polish could work if you have a woman around...

Greetings -- I just ordered the 0800,225.0700 Eibach coilover spring from summitracing.com for my 2015 dl650xt for $73 delivered, plus the spring adapters from racetech.com for about $57; the adapters are cheaper at procycle.com. use the spring rate calculator at racetech.com for "street" riding, not "adventure" riding. otherwise, you spring will be too stiff for your weight. for my weight (160 lbs), the race tech calculator estimated a 12.5 kg/mm which is equal to 700 inch lbs.

kg/mm to lb/in Converter, Chart -- EndMemo using this calculator, the race tech spec for a 13.4 kg/mm is equal to the Eibach spring 800.225.750. order it using those specs at summitracing and save $70 on the racetech price. for 12.5 kg/mm or 700 inch lbs, order the Eibach 0800.225.700, etc. the first 2 numbers on the summitracing order align with the racetech specs for the spring dimensions: 8 inches x 2.25 inches

I weigh 160 lbs naked. However, when I'm dressed with my cargo in the top box and pillion, I weigh 250 total. with preload set at 5, my sag is 70mm versus recommended 40mm. the front sag is fine with 2 lines showing on the front forks, versus 3 lines in stock condition.

There re are many posts on this thread where riders give their weight, etc and explain how the different spring rates worked out for them. RoosterMan weighs 190 lbs and used an 11.6 kg/mm. He had to set preload at 3 lines on the shock to get the correct sag. He would have been better off with the 12.5 spring, so that he could get the correct sag with no preload. Based on his specs, I opted for the 12.5 kg/mm or 700 inch lbs spring.

happy trails.

Update: Before rebuilding the shock on my 2012+ dl650, rear sag with preload set a 5 lines was 70 mm for the following weight: 160 lbs naked rider, 185 lbs dressed, 35 lbs for carryon tools and bolt on accessories, 30 lbs for the top box, and 15 lbs for the pillion bag. Total 265 lbs. Initial results show that by installing a 12.4 shock spring and setting preload to zero, my rear sag is 50 mm without the top box and pillion bag, and 55 mm when i add those 45 lbs. by adding a bit of preload, the spring should be perfect for a solo rider like me. Plus, I should be able to add the weight of the side cases, etc.

for my 2015 dl650, i purchased the EIB-0800.225.0700 shock spiring from Summit Racing equipment. The Eibach spring was delivered for $73. 0800 is for the 8 inch length, 225 is for the inside diameter, and 700 lbs per inch is equal to 12.4 kg-mm.
https://www.motocd.com/cogent-dynami...te-conversion/

Summit Racing also offers ….600, 650, 700, 750, 800…etc. Simply enter “eibach 0800.225.0700” for example, to identify sellers for that spring. RaceTech.com and Procycle sell the same Eibach springs for almost 2x’s the price.

I also purchased the required spring bushing and spring collar from RaceTech.com, both delivered for $52 total. If you use the RaceTech “spring rate calculator” for the DL650, the bushing and the collar you need are shown as required adapters for the (eibach) springs they sell.
RT - Digital Product Search

To orient those 2 adapters on the new spring, check out the images provided by fireclimber. He shows the new adapter on top of the old adapters and then the finished product. Use this information when reassembling your rear shock.
https://www.stromtrooper.com/mainten...p-abs-wee.html

Some folks indicate the spring rate for pre 2012 DL650 is 8.2 kg-mm and 9.2 kg-mm for the 2012+. RaceTech shows the OEM spring rate is 8.2 for all years of the DL650. Most agree that the DL650 (and most bikes) are stocked undersprung. So anything better than 9.2 kg-mm is an improvement for the 2012+. The trick is to get the spring rate that is correct for your weight.

Some folks that claim the RaceTech spring rate calculator is too stiff for the sag numbers you want. You’d likely want sag for the “dressed rider” & no cargo to be 35mm with zero preload or maybe one or 2 lines of preload. For my 160 lbs naked, some implied a 10.3, 10.7 or 11.6 kg-mm would be best. Again, anything higher than the stock 9.2 shock spring would have been an improvement. Procycle.com sell dl650 shock springs from 8.0 to 16.1. Go figure.

I used the RaceTech calculator entering my naked weight 160 lbs and left all other items unchanged i.e. street, intermediate/b class, standard stiffness, not lowered. The RT calculator indicated 12.5 kg-mm as the optimal spring rate for me. If I had entered “adventure” versus “street”, the calculator would have called for 13.4.

Removing the shock spring from the 2012+ is very simple, except my SW motech center stand was in the way of the lower shock bolt. I used my dremel to cut out a piece of the center stand. There was no problem getting the preload adjuster past the ABS unit, as was the case for the pre 2012. If you remove the preload dial, which is not necessary, 2 tiny springs and ball bearings will pop out. I took the shock, the 12.4 eibach shock spring, the two adaptors and pictures showing how to orient the adapters — to the local moto shop. They swapped the spring for $50.

I picked up the upgraded shock and noticed the spring was slightly off center, so i hit it with a rubber mallet and it seated correctly. The only glitch on the install was that the slots for the upper and lower shock bolts were not parallel. After installing the lower bolt on the shock, i used a long screwdriver to reorient the upper shock slot for the upper bolt. It slid right in. Study your service manual. At the top of this link, guitarhack does a nice job of illustrating how to do the job. Also, check out Black Lab’s pictures at:

happy trails and thanks for this great thread.
