I have a 08 SERK. Does the SE3 have the leather bags or hard? The BiTubo's will not fit with the leather bags (I tried)
I ended up going with Ohlins in the rear and Progressive Monotube's in the front. I felt the Ohlins were a better choice as they are serviceable anywhere, and in my opinion provide a better ride. They are also quite a bit easier to setup. There is a local race bike shop here that dials in suspensions for $40, and it was a waste because they came from Howard (the best HD Distrib for Ohlins) perfectly set. He has a whole order form w/ height etc..
The monotubes were a easy choice. Any mechanic can put them in with 2hrs labor, they are warrantied for life and they handle so much better. The customer service has been great, as I blew a seal and they sent out a replacement asap.
Of course this is all my opinion. I ride the bike very hard and worry more about grinding off my floorboards then the bike not being able to handle it. They also give a much nicer ride on the road as well. I have 2 settings for the Ohlins for track or 2up road and they are easy to change. I cant compare to the BiTubo's as they wouldnt fit, as I had the leather bags.
All I can say is I get some weird looks on the local tracks with my bags and windshield off going around the turns
