AIM Light Force Slave Cylinder For The Hydraulic Clutch.

[MDO]

While we were talking about the 2018 HD clutch recall, has anyone tried 1 of these on the M8?

It's the AIM Light Force Slave Cylinder for the hydraulic clutch. It's advertised as reducing clutch pull by 40%

Nice looking unit

HD could learn from this

I agree Jack. I was really impressed with the 40% reduced clutch pull, and then I saw the price.

I was thinking $175 & then I saw $280. I wish I wasn't such a cheap SOB!

I like a real fix, vise the adjustable levers that I heard work well. They are pricey too.

Really interesting.... They have a number of engineered improvements/enhancements.... nice catalog of goodies

I agree, they have some nicely engineered goodies. I like the clear/see-thru derby cover.

I think Jack's correct, HD should hire them as vendors?

Their website says during Sturgis & the Las Vegas bike shows, they were offering free installation on their variable pressure clutches & reverse gears.

Thanks for the link Michael,

I can see that reverse gear modification in my Freewheelers future if the electric motor craps out...

It was posted on the HF forum that the AIM light force cylinder does not directly replace the HD OEM part, but it's close. Buyers have been able to get the line hooked up with a minor adjustment.

The company stated they are making minor modifications to the units that will be available after mid January, 2019.

Everyone that has one is giving it rave reviews! Most are reporting that they can find it on EBay with free shipping & 15% off using an EBay app. That would bring it to $238.

The reviews also state that most feel it a better than 40% reduction in force and it's more like a 50-60% effort reduction.

I want to see the long term durability of this unit before I spring for it.

After trying Oberon levers I put the AIM Light Force slave cylinder on my triglide in November. I had to add a little curve in the steel tube end of the hydraulic line to make the exit from the cover line up. This was easyily done after attaching the line to the slave cylinder. It took a couple of flushes to bleed it completely.

The results are amazing. I would say the clutch pull is now reduced by at least 50% and the engagement is much closer to the grip. The clutch now feels better than my Twin Cam.

Yes it was expensive, but I have a weak left hand as a result from a stroke a few years ago. This one upgrade has made my new trike feel much safer and is the best upgrade I’ve done to it. If you are thinking about this upgrade I highly recommend it.

Thanks! I’ve been poking around here for a few months and have been on the HDForums for years but wanted to share my experience with the AIM slave cylinder. I recently bought my TriGlide after years (55) on two wheels and was very disappointed in the OEM clutch. Researching potential solutions I discovered all of the rave reviews in the M8 section of HDForums. You sould go there if you would like more information.

one fingered clutch pull demo'd near the end of the clip....

And a PS.... This is from another forum, but the source is a reliable guy and I thought you might like the data.....

"For those that are interested in some quantitative info, I performed some before and after measurements. Using a hunting scale, it took 14 lbs of force, in stock form, to pull the endof the lever to the handlebar. With The AIM cylinder it only took 8 lbs of force.

I started the bike up and the clutch does disengage fully and neutral can be found easily.As for the engagement point, the stock setup started engaging with the lever 2.25 inches from the handlebar. With the AIM cylinder the engagement point was 1 inch from the handlebar. This made it a lot more comfortable having all fingers wrapped around the lever. It resembled the engagement point of the old cable clutch setups. It also seemed to engage a lot more gradual.

After going for a short test ride today, all I can say is WOW! This is a triple win. Not only is the lever force really nice and easy, the friction zone is wider making it a lot easier to modulate, and also the clunking feedback in the lever from the transmission is essentially gone during a shift. ​​​​​​​​​​​"
