I was rereading the Decmber 1989 issue of Classic Bike. they test a MG V7 Sport. they claim 52 bhp ( MG claimed 70bhp) and 500 pounds. top speed of 120mph
seat height 30"
wheel base 57.8"

my 13 V7 compares favorably with 2 less hp and 100 fewer pounds

Classic Bike liked the R90S a little better and declared the MG a better sporting machine

[Sheepdog]

I thought the power claimed by MG (for both bikes) was for crankshaft horsepower, not rear-wheel horsepower. (the technique used by bike mags).  A loss of 15% of an engine's crank hp (due to friction) is common with shaft-drive bikes...

Often Magazines are wrong.... i remember when the stelvio came out , the mag were saying the stelvio was way heavier than the GS , but i remember few members/owner here prove that they were wrong .

Don't the newer V7s put out about 40-42 hp at the rear wheel? So, down about 10 hp and 15 mph or so top speed.

I've always been a bit dubious about the performance claims from that era . The Original V7 Sport cant have been much faster or quicker than a good R75/5 , maybe 107 mph .

I can't say anything about the declared HP but i can tell for sure that the v7 sport was waay faster than the 75/5 ( i owned both ) and they are like night and day.

Regarding the max speed my V7 could reach easily the declared 200km/h.

I am just going by personal experience . At one time in the early '80s , was part of a small riding group that included an R75/5 , a really nice low mileage V7 Sport , an 850 Commando , and my slightly modded '77 T140V . They all possessed almost identical performance , dunno .

I have to admit i am biased when comparing guzzi with other bikes.... :) but the V7 120 mph declered were real

Never owned or ever ridden a british bike..tho.

It would have to be a very big hill for the current sb V7 to teach 120mph. It's more like 105-110. The currents are 38-40 rwhp.

My first Guzzi was a 73 Sport. I traded a 750 Norton Combat for it, it was 1977. I was a punk college student with no money and less fear. The Commando was a very quick bike, just under 13 seconds in the quarter mile stock, it would kill the Sport off the line. But, the Sport was way more capable and steady at speed. I was out riding with a couple friends one night. We had pizza in a neighboring town. On the way home my friend on his CB750 took off from the last light heading out of town, the next buddy on his 850 Commando followed. Since I had my girl friend on the back, I gave her the "hold on" tap on the hands and rolled it on. As I caught the Norton, I shifted into 4th then pulled along side the Honda and hit 5th, and rolled past him. They both told me later that they were topped out. How fast was I going? Faster than them, that's all I know. I'd like to see the dyno chart for a stock V7 Sport because I just ran a 2014 V7 Café at a local shop and it pulled 38.4 HP.

[Aaron D.]

I know from experience a V7 Sport had a higher top speed than any stock Commando, CB750 (sohc or dohc) or even a breathed-upon MV600 with clip-ons etc. A 75/5 isn't close.

The funny thing was, shortly after that night on my Sport, I rode it home to Chicago, 350 miles. I noticed a rod knock when I arrived. I pulled the pan in a friends garage and found babbit flakes. I replaced the rod bearings and rode back to school. That winter I tore the engine down and found a severely worn cam, the number one exhaust lobe was about 1/4 shorter than number 2. I replaced the cam, case, oil pump, had the crankshaft reground and new main and rod bearings. I sold my pickup to finance it. Stupid college kid that I was, I tossed the case without stamping the numbers in the new one. So, if any of you find a 73 sport, with no engine numbers, it could be my old bike. I sold it to a guy in Tucson in 1980.

[redrider]

In 75 I owned a Kaw 400 triple. Port, polish, chambers-The Denco set-up. Supposedly good for 62 rwhp. I made lots of enemies among the CB crowd. It was a slugfest with the Hondas being the slugs.

One day on Carter St, a 76 Commando(white with blue and red striping) simply waxed my butt in a roll on. Never could catch up.

HP is a sales tool. I prefer the crank measurement. It is the most correct, IMO. RWHP is not exact-change the gear ratio at any point in the drive train and the numbers will be different even with the same engine.

The calculated top speed at redline (7200 rpm) and with stock tires is 113.2 mph for the recent 5-speed V7 models and 115.2 mph for the new 6-speed ABS models.  I have no personal experience about whether the bikes will actually go that fast, but my '13 V7 Stone sure gets me up to 90 mph quickly on a flat road with no tailwind, and seems to be accelerating well at that speed.  I'll leave it to braver and younger riders to report how much faster these bikes can actually go.

who said that the new V7 max speed is 120 mph ? NOT me .

I was talking about the ORIGINAL V7 sport, and yes , no need to go downhill to get 200 all'ora with that bike.

[oldbike54]

Fellas , I never said the V7 Sport wasn't a bit faster than an R75 , but does anyone have verifiable evidence that they would run a true 120 MPH .

[yogidozer]

Let's just agree....it's fast enough :-)

we should address this question to the V7 sport owners on this forum , they should now better...or ...sadly those bikes are just "garage queen " ? ;)

Me, too. Great shot..

[Aaron D.]

I am pretty darned sure a V7 Sport with fresh plugs would do 120. It required being flat on the tank.

If you believe a CB750F DOHC would do 115, then I know a  V7 Sport will do 120 because I watched one absolutely walk away from said Honda during a looong straight with a bunch of bikes pinned for miles.

Verifiable? Maybe the old MIRA tests from one of the Brit bike mags-Mike Nicks had an 850T as considerably fastet than a Commando. So maybe we can find that.

Michael D still rides his , and if he would answer his phone or Emails ... ;D

having ridden with him on my Greenie, it is a surprisingly fast little motorcycle.

I am still watching you!   ::(

Thanks Marco for posting this, I ordered one from Photobucket. I had seen this photo years ago and in my memory, the other bike was a BMW. Maybe I'm thinking of a different photo. However, the question is, who is over taking who in this shot? As a life long Guzzi rider, that Laverda rider looks awfully surprised!

My 1973 V-7 Sport I bought new was specified top speed in the manual of about 129.5. And I remember it would go that fast or close to it. Handling was great, too.

Nico Cereghini wasnt surprised, methinks, as he was the original test rider/ journo for Motociclismo when the V7Sport was featued in print. He also had plenty access to Moto Guzzi at the time. Brambilla, OTOH, was a pro racer that had serious time on the GP circuit , so Cereghini probably had a "dang ,here he comes !" look on ....just wish I was there

[jabberwocky]

Those of you who are confident that the V7Sport will do 120 plus, what is your evidence? You know that the speedos are notoriously optimistic, don't you? I'd be pretty surprised if one would do an honest 120 by timing or radar.
