Just brought home my new T120

Finally went out and exercised the checkbook and bought a new T120. After riding my 2007 T100 for a year the 120 is quite different in sound and power. The gear ratios are quite different, and the power curve is broader than the 100. The 270 degree crank setup makes for a very different sound. I still can't reconcile how a 270 degree crank would work, how it benefits the power and smoothness of the engine.
Lead mechanic at the dealership told me that the crank configuration allows better "tire recovery", meaning power pulses from the crank allows the tire to recover (?) during the pause in pulses as the crank rotates or some such. Never heard of tire recovery, and I kind of doubt that is the reason why Triumph designed this engine.
It's not as smooth as the 100 with the 180 degree crank. It's a great bike, the 120, and I know I'll enjoy it a lot, I do love having that 6th gear, but the crank configuration, anybody have a better explanation of why the heck that benefits?

True, the T100 is a 360 crank, I knew that, just, well, you know.

According to the head mechanic at the dealership the T120 engine has been counter balanced to smooth out the irregular firing order. I have yet to really take a long ride, weather's going to be good this weekend so I plan on logging some miles. I will post a few pictures tomorrow, if you guys will forgive my tardiness in that area.

I'll report back soon.

I learned, by reading the owner's manual for the new 120, that the current stock of 100's had the 270 crank as well. Thanks for the video detailing the attributes and design practices of the 270. I also see in the manual, which is a generic covering both the 100 and 120, that the gear ratios between the 2 engines are identical except for the addition of a 6th gear on the 120. My '07 100 has quite different ratios than the new 120, and as the new bike's ratios are taller than my '07 100, I kind of wonder what the new 100's pull like, with a less powerful engine and the taller gears.

Having only about 50 miles on the bike as of right now and having not been on the interstate as of yet, I have only gotten into 6th gear only once (secondary road riding). It still has lots of pull in 6th which speaks to the power of this engine. Today is going to be a good weather day and I will spend some time on the road. So far I'm loving it.

Cruise control, after market, where do I find one? Yesterday I rode the 120 about 250 miles all on secondary roads, from eastern Vermont over to New York State, Crown Point, where there is an old fort that my wife and I used to visit. Then rode east over Lincoln Gap road, going toward Warren, Vermont, a very twisty mountain road. Is this weekend a big motorcycle weekend? Must have seen more bikes than cars, large groups for the most part. Ran into 2 guys from Toronto who were out for a 5 day ride they do every year. Both had fine looking BMW's.

I did use 6th gear a lot yesterday. At 60 mph the engine loafs along at under 2500 rpm. What a fine machine. I'll be riding today, too, not nearly as far though.

There are lots of throttle locks available, but the only after market true electronic cruise control (CC) I know of is this one:

It's very expensive, and it looks like it's not made for the T120, probably because the OEM T120 cruise control kit is far less expensive, under $400. Triumph's CC is already completely integrated into the design of your bike, including a CC icon on the right instrument screen, and a green "CC active" light on the tach face. All you're really adding with the CC kit is a switch and a couple of wires, though the kit replaces the entire left switch grip housing and switch plate. You can install CC yourself, if you've a mind to (I did), or let the dealer so it. Only a dealer can activate CC.

Here's a little about CC, from when I first installed it on my T120:

Here's the T120 CC kit, before installation. The photo is of the "rest of world" version, with headlight and DRL switch. There's no need to remove the left grip during installation.

I am interested in the Triumph CC system. I'll be going to the dealer next week for the initial check on the bike and may ask about it. I usually avoid interstate riding but I do get a cramp in my right hand during a long ride. I think I have some arthritis beginning in that hand after years of working with hammers and hand tools.

So far I am loving this new bike, it just goes, handles well, and just feels right.

Given that you've mentioned the gearing in a few previous posts, you might consider changing the stock 37-tooth rear sprocket to a 39-tooth. It is a popular change on these T120s and I really liked the adjustment to the gearing that resulted from it. You can search for previous threads that have hashed this topic out thoroughly.

I put the Triumph CC on my Bonne T120 last Sept. prior to going on a 1400 mile 8 day road trip, and it’s been the best mod I’ve done to the bike. Second best was the JW Speaker LED headlamp and third was the Corbin seat. The x-pipe, pipes, mirrors, and all the rest of the mods I made are just eye & ear candy, but those 3 things I mentioned first are what actually makes my Bonne more enjoyable.

Good choice in the T120 . Rode my 2016 T120 on route 100 in VT from the Grey Ghost Inn north
for about 115 miles last summer turned around and came back to the Inn .Fantastic road ! Also a couple other side trips.Love the bike !SW bags installed , and skid plate after I bottomed out on some dirt road ruts and broke the side stand spring off which shuts off bike when stand goes down .Sacrificed a shoe lace to tie it up and went on !
