Interesting question, or two.
I've had to think about this. I can make a case for either.
Kind of like kids, they each have their own personality.
The 750 is a freshly built Combat, 20 over, 34mm Mk2's, Tommaselli quick throttle,
L/R iggy, fresh tight gear box with the 19 C/S, standard ratio primary, it just rips.
Will embarrass a lot of modern stuff if they are sleeping.
The 850 is the run of the mill stocker with fresh Premiers, standard throttle ratio, Basic (lazy) Boyer,
21 C/S with standard ratio primary upgraded Master and a Hydro clutch. Gear box needs work.
Not the fastest thing around, but can hold it's own, run 75 + all day.
It also brings me back to my youth as my first Commando was a NEW 73, 850 in Blue.
First new anything.
I have 5 M/C's. I get asked all the time which is my favorite. My stock response is whichever I am riding at the time.
I was thinking about the Norton's when I went to sleep last night thinking I would have the answer in the morning.
When I flipped on the garage light this morning, it was apparent. Of the 5 M/C's I own, one jumped right out and put a big smile on my face.
The Sparkly Blue 850, for no other reason than it makes me smile the most.....
