Default M8 107 over the 110?

I am considering selling my 2012 Ultra Classic CVO and upgrading a few years to the 2017.
I know the 2017 has the Milwaukee 8 107 in it. How will this compare to the 110 that's in my 2012?

im about positive the 107 was designed to run on par with the 110 power wise. the first year 107s seem to be kind of hit or miss with sumping problems so id include potential repairs in an offer if issues havent been addressed, but engine aside, theres a bunch to really like about the rushmore bikes. im sure someone will be right along to tell you the 107 is 100x better than any twin cam ever, but imo between a 107 and a 110 the engine isnt the selling point, the rest of the bike is.

My stage 2 107 will run circles around a TC110. Its a late 2018 model and no issues. Sumping mostly only occurred on stage 3 builds due to increased crank case pressure.

M8 has a flatter torque curve then comparable TC engines. You can see that on @fuelmoto website, and when you add a stage 2 you get a lot more bang for your buck.

definately correct on the flatter broader torque curve even if i feel like its too low in the rpm range. im hardly ever under 2500, never under 2k unless im slowing down. as far as stage 2 107 running circles around the stock 110, i wouldnt ever imagine a cammed 110 would be able to run circles around its stock self. i dont have a single thing against an m8, but the riders sure act like its a rocket ship compared to anything else

Apples to apples stage 2 107 is a lot more powerful than stage 2 110 I have owned both. The 110 runs hot

just like the 103ho with its couple more hp was life changing over the standard 103 and the 107 with its few more ponies was the end all be all compared to a 103ho. would it kill the m8 guys to be a little less full of crap?

Your stock 110 TC will be about the same or very slightly better than a stock 107 M8. I have ridden both in stock form and that was my perception. The 110 I road was a 2014 RK CVO.

As a side note, there are very few 2023 models with a 107 motor now so it could be on it's way out real soon. Just sayin'.

This is all very interesting, I remember the hype revolving around the M8 107 and it's torque. I was drooling in the showroom anticipating one day owning the M8 107.
But what RKZen said rings true, when was the last time I saw a 107 in the newer bikes? Could they be phasing it out? With the way prices are,
I don't think I have the $$$ to step up to something more recent than a 2017. It's frustrating. The very last thing I want to do is buy something I'll have problems with.
In 2009, I bought my 08 Ultra with 1508 miles on it, which was a good thing, then I realized that in 09, they started making these neat changes. I still rode it for 30K
and then upgraded to the 2012 CVO, which has been such a great bike, with the exception of the rattling valve train. But I don't want to be in a position where I find
myself saying, "Crap, I shoulda waited and bought a 2019 with a 117 in it? My hell, analysis paralysis!

I'm in the same paralysis as you with my '13 King. It's a completely stock motor with the Rush Big Louies slip-ons.

Your statement on the 107 hype is true when comparing the stock 103 (non-HO) with a stock 107. I've been wanting to upgrade as well, but my King has been flawless since new. I've upgraded the suspension and seats. I have a TP and detached batwing and lowers, so it's a very comfy touring bike. The new bikes appeal to me but for the current pricing, well I can do a nice stage II on my King and have the same or better performance than a stock 117. I'm getting ready to put on some Rushmore H-D bags for a great deal and have put on some bling to keep me happy for a while.

Sorry to disappoint but a stage 2 103 will not even be close to a stock 117.
The key thing I noticed about moving from a twin cam to a M8 was the smoothness and and willing to rev, Im a convert, there is no comparison to how each feels and responds
