Looking to get a outlander is there a big difference in the 650 vs the 800 we mostly trails ride.
1. Power wise
2. size
3. any pro's or con's vrs the two
It all depends on what you are going to do with this machine. I rode an 800 and I own a 650 HO and I'll tell ya, I saw very little difference when riding in trails.
If you intend to work with it hard, then go for the 800 , there is a few horsepower extras on this one than the 650.
Personally, 650 HO EFI is the perfect engine for me for trails anyway.
