This is a very old thread, but thanks to Thumper 650, it has been revitalised just at the point when I'm looking for info about Pegaso's!
I've been offered a bargain Pegaso yr 2000 but the bike is actually 150 miles away so not easy just to pop over to see it (esp with icy roads in the current bad weather).

I've spent hours trawling the internet looking for info to compare the older models vs the new models. Now there are 3 variations with the Trail version being promoted for off-road.
But a 2000 model? Is that suitable for off-road?
Only talking about gravel, dirt and grass tracks - not mud or riding up rocky mountains!

I very briefly had a Pegaso earlier this year.

I can tell you the bike is very good to ride and does work on light off road and trail riding, It's like all 650 Trailies a bit heavy for the really technical off road.

But my ownership was brief due to an engine problem.

When the garage who sold it to me eventually got to the bottom of the problem I had got to the end of my teather with them.

But It's worth noting my problem was with a temperature sensor in the engine causing it to run very high on revs and eventually disintergrated the gaskets. This was probably and individual problem relating to the specfic bike.
