Looks like the gen3 is a pig.
I like riding both my pig and my old gen 1
When ridden back to back, they are quite a bit different. Seating position is a lot different, power delivery a bit different.
Gen 1 has less noticable drop in power after 8-9k rpm. Gen 3 has flat spot up to 3-4 (euro 5 probably), but it's nice at low speed. Then pulls hard to around 8-9, and then hits a wall.
Probably the biggest difference is in handling. Although, that might be 20 some year differencein shock and different tyres.
