Had a Series II Le Mans for a brief period years ago , nice bike but ... parts were unavailable and through the roof expensive. Agree it's a nice looking bike , so is the Griso but my experience with Guzzi's would stop me having another one. Bloke i know had the Guzzi dealership in Brisbane for a couple of years , told me it was a nightmare getting parts ... so not much has changed over the years by the sound of it .
Riding them is an enjoyable experience for sure. Took a new Griso for a two hour demo ride up the Black Spur in Victoria (Google it ) loved it... but owning one would be somewhat less enjoyable were anything to go wrong.
The guzzi shop at nerang had a ride day 3 months ago .i took several of them out for a ride to be honest they handled nicely braked well but power wise they just don't do it for me although the new 1400 looks like a bit of a weapon .
Nice looking bike it even has knee rests on the engine for you if you think Triumph dealerships are few and far between wait until you go looking for the guzzi ones.
My Triumph dealer is 5 miles away and he also sells Guzzis. I'll take a look if and when they get one in. But, I'm guessing those cylinder heads might be a bit too close for a normal sized human.
