|So you're sick of the Boge-Sachs shock on your Ducati? I was too and always dreamed of an
Ohlins, but at $600+ I didn't give it much thought. Then I saw a slightly used Ohlins rear
shock from a Ducati 888. Since the Monster frame is a almost a direct take-off of the 888
Superbike, I started doing some digging. I found that the stroke and overall lenght, plus the
hookups and reservoir were the same as for the Monster. Only difference was the spring rate
and damping. Some gurus expressed concerns over the harsh damping being too much for the
Monster because it was originally set up for a heavier bike. But, since I am about 195 with
gear, and the Monster is a more rear-biased bike I decided to be the guinnea pig. Well, I can
tell you after about 2,000 miles that I have had no problems. The shock works great.
Honestly, I wish I could get a slightly stiffer spring so there's not so much sag, as it stands I
have to set the preload mre than I should. In any case, I picked the shock up for $250 and it
bolted right on.
|The first step is to support the rear of the bike. But, you can't use a stand
because you need to unload the suspension completely so that the swingarm
drops down enough for the shock to drop out. I used a pair of jackstands
and a solid steel rod that I stuck through the hole in the swingarm pivot.
The rod is supported by the stands, and it allows the swingarm to drop down
and hang there. You can also use straps from the roof to support the
frame, but I think this method is easier.
|I'm kind of glossing over all the steps as you may notice, but since this is
sort of an advanced operation I have to assume you know how to do all
the side ventures. Strip the rear down to gain access to the shock pivot.
This includes removing the rear tray and side panels, etc. Then you can
start to undo the shock bolts.
|At this point you can unbolt the suspension arc, using your wrench
and a allen on the backside of the bolt. Careful, cause once this is
unbolted the swingarm will want to drop down quickly.
|Now for the hardest part- getting your 8mm allen into the lower shock
bolt. It's tough, but possible. Once you get it loosened and start to
unscrew it you will notice it starts to run out of clearance.
|I switched to a 8mm allen socket (there's not enough room for the
ratchet), and used an 8mm wrench to turn that the rest of the way.
|With all that unbolted, the shock slides out. The Boge is a little
easier to get out than the Ohlins is to get in, so don't pat yourself on
the back just yet ;)
|With the suspension deisassembled it is a great idea to perform the
lube service. Remove all pivot shafts and carefully inspect the
needle bearings, etc. Re-grease with fresh lube and clean it all up.
|Now, CAREFULLY wriggle the Ohlins in there, reservoir and all. It
is a good idea in hindsight to tape up the reservoir to prevent
scratches. I wish I would have : (
|Once in, be sure to lube the top and bottom
mounts to prevent wear and noise.
|Now you'll have to tighten the lower shock mount using
your best abilities to guess the torque. A torque wrench
won't fit in there, so do your best.
|Torque the suspension lever mount and shock and arc bolts
down. The 10x1.5mm bolts/nuts are torqued to 37Nm.
|The Arc-Joint nut is torqued to 22Nm. I'm kind of fuzzy
on which one this is, but it's listed as 8x1.25mm threads.
|Finally, find a spot to mount the reservoir. This is crude, but until I get a
better mount (the one from an 888 doesn't seem to bolt to anything), this
will have to do. Now set the sag and you are done!
|The Ohlins rear shock is a great upgrade. Compared to the Boge, I can run down a fire road very smoothly, but the rebound
and compression damping is enought o control the bike without making it harsh. It is a much smoother unit than the Boge,
and is infinitely rebuildable. There are much more settings as well (about 30 for compression and rebound, compared to the
10 for rebound on the stocker). A great upgrade and if you can find one used (read: cheap), all the better.
