Hi all,

New guy here to this forum and had a question.
I am looking to buy a HM Quickshifter lever style. I live in Chicago and can't find a retailer except for in the U.K. or Australia.
Does anybody know who sells these in the USA?
I heard that there was a lady named Mary that sells them here and I emailed her but my email was returned.

Also, what is the advantage of the Plus SS compared to the regular Plus?

Any help would be greatly appreciated.

Jack

You may be thinking of the company called Annitorri who used to carry HM shifters. That's where I got mine. Great service there but they no longer carry the HM shifters. They sell a simpler shifter that is less expensive and a lot less adjustable. I haven't heard any reviews recently.

There is a US company on FB. There is their phone# on the side. I do not see a website.

Every gear change is different. The seamless shift technology dynamically adapts ‘kill time’ and other parameters in real time to provide the perfect shift – regardless of RPM, load, rider style or gear. .....first we offered the revolutionary and only digital strain gauge to the world which was an instant hit from cruiser riders through to world championship winning teams, now we have taken that technology a giant leap forwards with seamless shift.
.....It works by intense processing of the sensor signals using very advanced predictive math in the form of non-linear Kalman Algorithms. The same math and technology that guides missiles and computes the trajectory of Comets.

The strain gauge is a small cylinder that expands/contracts in response to strain on the shift linkage from the gear shift pedal. Depending on what mode you have it set for C-contract, E-expand or CE-contract and expand (if the model is equipped with auto blip for clutchless downshifts), the strain gauge causes the electrical contact that signals the ignition cut to unload the transmission so you can shift smoothly without using the clutch. I saw simpler DynoJet shifters that worked this way 10 years ago so I do not think HM invented it but they may have perfected it. The DJ shifters of old were not very good but I hear no complaints now.

PROBLEM: What if you put enough strain on the shift pedal to trigger the ignition cut but not enough to cause the mechanical shift? Also, you may find that some gears switch smoother from a longer kill time and others shorter but you only have one kill time you can set. To complicate things further, rpm comes into play when selecting an optimum kill time.

My HM Plus works good. I have it set for 65 ms kill time. I have played with different kill times and sensitivity settings but I did not succeed in finding a setting where I never miss a gear under all conditions. I love it but if you go with the HM Plus, the best advice I can give you is MAKE SURE you kick that puppy into gear hard and really fast. The kill time won't wait for you if you are timidly lifting on the shift pedal. You miss a gear it goes into false N or slams back to the previous gear. Yes, I chipped gear teeth initially and they came out in the next few oil changes . I'm very careful about how and when I use it now. I really enjoy it though. Might just be my favorite mod. I plan to convert to GP shift pattern (so now I will switch the E mode) which should help with making a definite upshift and I will mess around with kill time and sensitivity settings again. I have discovered that the PC5 has a very detailed quickshifter utility.....more in a minute gotta go.

...the PC5 quickshifter utility allows you to set up ignition and/or fuel cut as well as whatever killtime you want for each gear. I do not know if it will work with an HM but I plan to try it. As long as you can get a pulse through a wire to one of the the inputs on the PC5, I don't think the PC5 would know what kind of shifter it was. This might be a way of improving the HM Plus but I don't know how it would compare to the seamless shift feature of the HM Plus SS. It might be better than the SS for all I know. They claim the SS feature calculates the optimum killtime for every situation. If it can do that reasonably well, that's the one to have.

If I were to do this all over again, I would buy the HM GP. It's so much fun, I would love to have autoblip for clutchless downshifts. I'd pay the $900 for the GP and whatever the required blipper module cost. It'd be worth it.

I was in contact with HM in Kent earlier this year concerning their stand alone quickshifter. I liked their products,but wasn't happy with purchasing and support being offshore. I wound up installing a HealTech Quickshifter Easy. Not adjustable per gear, but very adjustable for rpm kill time, sensitivity and delay. Bluetooth setup is great, and updates from factory are uploaded automatically. So far I'm really happy with it..

Thanks for the information Rook. I will contact them.

Thanks SJG. I will check out the Heal Tech too.
