I took my 2015 VT750 Aero on two fifty-five mile trips this weekend. It's "sweet spot" seems to occur around 55 mph and I've heard that the fuel economy was taken at that speed. And what I've learned is that the v-twin has superb low-end torque, meaning an early shift - at low rpms. That's the nature of the v-twin and up until now I always felt that the Harley guys were bogging down their machines. (EDIT) In other words a v-twin offers way better low-end torque.

My '72 Triumph is a parallel twin, meaning that both pistons rise and fall at the same time, firing alternately. This bike wants to be wound out at the shift point, at high rpms. Bogging this this bike's motor is a recipe for disaster: burned pistons. When going up hill, best to down shift into a lower gear and run higher rpms otherwise you'll blow a piston. On the highway it's sweet spot seems to be occur at 65-70 mph. Again this is a differently engineered motor.

That's quite an age gap as well lol. I know I was reading a review of the new Bonneville speedmaster and it said most of its torque is on the low end. My triple.... well its sweet spot is 0-100

I have spent over 2 1/2 years wrenching on the old Triumph and bringing it back to life after setting in someone's back yard or garage for over 34 years. With the rolling restoration complete, the bike fired up on the first kick.

Yes except for replacement bulbs, some fasteners and also I upgraded the ignition to a Tri-Spark ignition. Eff points and condensers. Every knowledgeable classic Triumph owner advises to carry spare points, condensers, and bailing wire. To own one of these old bikes you'll learn who and who not to order replacement parts from!

(EDIT) For example, the filament headlight bulb for the Tiger is constructed with a "plate" that sets next to the filament itself for "proper" aiming/reflecting and only one vendor checks out these bulbs prior to selling them, Steadfast Cycles, and I had to wait about five months to receive one after ordering it. And no, a modern filament bulb won't due, not unless the original Lucas lens has been replaced with another design. Ownership of a classic Triumph therefore requires a true commitment to ongoing maintenance; and, it's made me a way way better mechanic than ever before.

As previously stated, ownership of the big T requires TOTAL COMMITMENT. Yeah, right, commitment to a mental institution as to why anyone would want to own one of these......"things":nerd::nerd::nerd:. Well, that's because Steve McQueen rode one for desert racing along with my step-brother and his father who were both championship desert racers way back in the Mojave during the 1960s.

....My triple.... well its sweet spot is 0-100
LOL! .. Y'mean these slightly de-tuned Speed Triples? ...Yup! :-D ...Second gear on my Tiger - off-road, is just astounding. Between 2mph and 50mph.. it just tractors-on through pretty-much anything as smooth as butter. Third and fourth gear? Makes power like water pouring from a bucket ..Just a Rocket-ship.

But you gottsta rev them a little higher than a v-twin off the line.

Loved my Aero. Great bike! 75-85 mph? It thrummed like a tuning-fork, could do that all day long without breaking into a sweat though.. Still kinda miss it a little.


"Baby" ..Served me well, she did!

I took my 2015 VT750 Aero on two fifty-five mile trips this weekend....
Congrats on your new scoot! :-D Glad you are enjoying it!
