frankly, i think it's boring. which might actually be complimentary to a "retro-classic".

...especially compared to similar examples from honda and ducati.

needs the 1000cc engine. I don't know if anybody has looked at specs but guzzi 750 motors make a whopping 48hp (tons of torque though). Heck even the bonnie has somewhere in the 60s and the ducatis are all breathing on 100hp. I really like the way this bike looks but guzzi is going to have to do a lot better if they expect to sell even 1 of them here. fortunatly for now it is a euro model only, but even the europeans like speed and won't put up with a 500lbs motorcycle making 48hp.

Wow, 48 hp. I knew they didn't make a ton of power, but thats just kinda sad. That will never compete with Triumph or the Ducks.

I was in the ducati/guzzi dealer yesterday and looking at the griso (my father wants to buy one - I was just dropping my bike off for service). and their 2007 grizo 2 valve 1100 (1064ccs) makes only 88 hp (2008 4 valve makes 110hp). It does make about 90 ft/lbs of torque however, which is really showing it's lineage as a tractor motor (the current line of guzzi motors actually comes from the major redesign in 1971 by Lino Tonti for the V7 sport). The original guzzi v-twin design was penned in the early 1960s, based off an agricultural design, and intended for an italian police bike. The original 700cc v-twins made 45hp, it is a little sad that in 40+ years it has only gained 3 hp.

the specs on the 750cc motor I got were from the brevia 750:

Breva 750
48 HP @6800
40 ft. lb. Torque @3600
401 lbs
$8000

the other bikes in class:

Ducati GT1000
92 HP @8000
67 ft. lb. Torque @6000
407 lbs
$10,000 (approx)

Monster 695
73 HP @8500
45 ft. lb. @ 6700
370 lbs.
$7800

08 Bonneville
66 HP @ 7200 451lbs
52 ft. lb. @ 6000
451 lbs
$7300

What I don't understand is would it kill Guzzi to put an 1100 motor in something like that v7 classic. Sure you couldn't call it a v7 anymore (v11 classic sounds nice), but at least it would have some get up and go. Or at least do a 4 valve head for the 750 that gets its hp more in line with the Bonneville's. The 4 valve heads (8 valve total) on the 1100 and 1200 can boost the hp up to 122hp when properly tuned (MGS/01). On the regular street bikes the 4 valve heads make about 100 hp in the bigger bikes.

My Thunderbird only makes about 70hp, if I remember correctly, and it's a 900. Makes gobs of torque though. It goes pretty well, at almost 500lbs. What's a sohc cb750 make? Somewhere around 50ish? And I'll bet that Guzzi isn't as heavy.
It is frustrating that all (most) of these "retro" bikes have detuned motors - especially mine. They hadn't come out with the Tbird sport when I bought mine.

if we are going by flywheel hp then a cb750 makes around 67 (some of the 78 Fs made closer to 70hp). Through drivetrain loss 67 turns into 50ish real quick. Factories rate their bikes hp through the flywheel so that MG will have a rear wheel hp of somewhere in the 30s. Ick.

The Guzzi Griso is 500lbs DRY. If going by the brevia's specs the new V7 shoud be closer to 400lbs dry (the brevia is 401).

What gets me is that Guzzi had a "small block" 750 4 valve head in the 1980s that made 65hp. They gave up on that motor at the end of the 1980s to revert back to the 2 valve head for reliability. Would it be so hard to bring back that head design to get those extra 20hp?

if there is one thing we can learn from this, it is that moto guzzis have a lot of potential. For a single head redsign to increase the bike's output by such a large hp number (as seen in the bigger motors)they must be seriously choked down. too bad not even the factory sees the good in more hp.
