History of the V7/V7 II

[omega1987]

Hello from a newbie and Breva 750 rider.

I did some research before buying my bike and the consensus seems to be that the Breva and v7 are mechanically pretty much identical but am curious about the power output as a number of sources rate the early v7 at about 40hp vs 48hp for the Breva, is this correct or just a case of inaccurate information?

P.s. I'm amazed to learn that the small block used in a drone , thanks Guido

Do a search on 'Drone' here. Some wombat in Indiana has one in a Lario chassis.

You're confusing crankshaft (48) and rear wheel (40) ratings.

The B7, N7, V7, and V7II are all in the same ballpark, though I'll say riding them back-to-back the 1TB models feel a bit stronger at lower rpms than the 2TB models.

V7 engine was basically the 750 Breva mill. Went to single throttle body a couple of years ago, less trouble there, yay. Then to the mostly all-new V7 II engine. Still Heron heads. ...

The V7II engine is identical to the last year of the V7I motor.   The transmission (6 speed) is what was all new on the V7II, along with ABS, traction control, and chassis modifications to lower the engine and transmission and make them more level.

The new shaped cylinder fins and heads and single throttle body arrived at the same time, 2012 in Europe, 2013 in the US.   This coincided with the V7 Stone and V7 Special models replacing the V7 Classic.

2015 (in the US, 2014 in Europe?) brought the wet alternator.

Dusty, you are right. I am confused. Get in and let me back up slowly. The V7 II had a predecessor called the V7. When did the Heron V7 appear? That had a small block developed from the old V50? The Loop and Tonti V7 was of big block design, enlarged to eventually 1064 cc. So we have two product lines calling themselves V7, one of which is now a V7 II. Am I approaching the truth?

  Heck , I live confused , more fun that way

@jas67 - that was off the top of my head and I'll admit to not knowing all that much about the newer ones. So a few changes each year. Makes sense. Otoh there are major differences between V50, V50II, and V50III engines and transmissions. Re: single throttle body having more low- and midrange -- same as the Brit twins, BSA & Triumph. Twin carb gets all the attention, single is better for riding.

There's so much great information in this discussion.

Thanks everyone, and especially Howard R.

Cheers

Small Block V7 Classic appeared as a 2009 model bike.
