Changing front fork oil & Ohlins forks

Two questions. First, has anyone changed their front fork oil on the upside down forks? I looked for a drain plug/screw and nothing? Years ago when I turned a wrench in a shop there was a plug at the bottom of the fork leg. Now? If there is no drain plug is it possible to drill & tap for a plug?

Second, has anyone totally replaced the forks with a Öhlins unit?

Winter time projects can now start in the living room. She sleeps inside of the house when it gets cold.

Are you asking about a complete new ohlins fork or just new cartridge?

Because I'm looking for a cartridge but I'm not sure which one will match with our fork (NIX 30?). Our fork looks really similar to the low rider S one, but I'm not 100% sure.

sntpz, thank you for answering. I will be more than happy to just get the cartridges at this point. Really want to upgrade to Ohlins. I know, trying to get 571 pounds to be a track star is not what a sane person would do. Ego, ok.

I am surprised that how little support there is for the Roadster from aftermarket vendors. Let me give you a few examples. First, e-mailed Bassani about their Rage III fitting a Roadster with Harley rear sets. Nothing. E-mailed getlowered.com, nothing. With getlowered I even included three photos so I could get their expert opinion on fit with the Harley rearsets.

The front brakes. Want to upgrade them to Brembo or Performance Machine. PM got back to me stating that by Spring they will get a Roadster in to ‘fit’ a dual system to. Brembo, e-mailed freespirits.it & Brocksperformance.com tonight for a full front brake system. Nothing yet.

As for Harley, not much from them but chrome.

Oh, forgot, would love to put a pair of Gaffer rotors on too

completely agree with you. I can't understand why this model is so 'rare' if at the end is just and sportster with few mods...

I purchased a detachable sissy bar a year ago and I had to return it because our rear frame is thinner than the normal sportster (no chasis covers) and there are no many options on the market.

I'm going to customize my roaster into a light performance cruiser during the winter (FXRT fairing, brembo m4 calipers, brembo rc19 master cylinder, ohlins/legend/andreani full suspension upgrade, etc..). For summer I will keep the performance parts but will come back to the stock cafe racer look (with rear controls).


I will share here everything in order to help other people to find fitting parts and info.

Should have added the Harley tuner too. From what I can find there is nothing for the combination of a 2 into 1 exhaust and a low restriction air filter. I do not know if the Harley tuner has an option in their drop down selection either.
Will keep you/anyone here with updates.

I upgraded the cartridges to the fully adjustable GP Suspension. It turned out to be a bigger job than expected and not sure the benefits equal the cost. I haven't tweaked the comp/rebound enough nor done any track time.

GP Suspension, 25mm Cartridge Kit

For brakes I found upgrading the front rotors and pads with a Lyndall set was a substantial improvement. I upgraded the rear as well by increasing the size of rotor to match the fronts (a new rear caliber bracket is required- message Jacob_conrad on instagram as he makes them). My rear has far more stopping power now!

In terms of tuner I use the FP3. Its taken some trial and error, especially since I added new cams, but their support team is amazing and worked to change/tweak maps.

Is that Jacob_conrad that has ‘material boy’ on his page. I do not have a Instagram account but just did a search.
