    Theyre Type S36P (S36PR1C1LB), but a variation of. I worked direct with Ohlins USA on the desired dimensions/specs and they built them up. They couldn't get the length vs stroke needed with the rebound damping wheel, so removed that and just have a screw adjustment at the bottom.

    20-28N/mm springs I started with were too soft. Now trying 24-33N/mm tonight. EDIT: 24-33's too soft also. Shooting for ~1/3 travel sag. Moving on to new springs...

    Love your build and website. Out of curiosity, would the swing arm extensions have worked if left bolted in place? They appeared well made and may have done the job more than adequately. I have seen aftermarket extensions for some sport bikes; was wondering that it might work well for a ADV sporty. Might also be a little more economical.

    Regards

    I don't think economy was a major goal for this project :deal

    I don't think the extensions would be a good solution - at least the way I made them. They would probably need another bolt to stabilize them instead of just the one bolt at the original axel position. Then drilling a hole in the swingarm for that bolt would add a weak spot that may crack in time. Maybe for mild riding they might last, but I wouldn't trust them for hard core dual sporting. That being said, maybe theres a different good solution out there for a bolt on extension....? Also, when you extend the swingarm, the brake caliper moves to the new axel position and you may not have enough or any of the stop bracket left to hold it in place. That would have to be addressed.

    Ramon is right. This build was about building a dream from a vision and probably a bike I will have for the rest of my riding days. So, economics went out the window long ago :lol3 :D :cry :clap :freaky

    The rear shock springs are now dialed in. Took three sets to get it, but its done.

    Heres a pic. Full bike pics this weekend...and a long awaited ride

    I'm surprised you mounted them with the reservoirs pointing forward. The "usual" orientation is with the reservoirs to the rear.

    That knob might have something to do with the orientation.

    They actually fit both ways, so I had a choice. I thought whats the best way and why. The reason I chose forward was for mass centralization & I liked the look this way. Didn't see any negatives, but if there are any concerns out there - let me know.

    I know the mass centralization argument is weak given its a big heavy bike, but at least its a reason. I see a lot of the higher performance cars mount their brake calipers towards the center CG - maybe for the same reason (?) or other like air flow / cooling???

    For instance...

    Finally finished the suspension tweaking and went for a little test ride in the hills today. Only stopped to take a few pictures and to adjust the rear spring preloads. Too much fun :ricky

    Now I need to clean it up a bit for the Quail Gathering next Saturday. Then after that, its time to do some dual sporting and get it dirty.:muutt

    Here are some pics of todays test ride...

    To bad the MOCO wont/doesn't make what you've made, wow nice bike. If I had the funds I know who I would commission to build my offroad Harley.

    Stunning Jimmy.

    Some more luggage and a bigger windscreen and you could REALLY have a long haul Adventure bike there. but it is perfect for what you built it for, day long adventures.

    So tell seriously, have you ridden any Boxer motored BMWs? How would you say the motor in the sporty feels comparitvely for this type of bike?

    My dad had a 1993 Sporty 1200 and I found it a vibratey compared to my '03 Dyna and that was not as smooth as my Boxer, but with this different suspension and wheel set up how does it ride?

    Gorgeous no matter what.
