The TE511 is significantly better offroad (no comparison).
The WRR is significantly better on-road (no comparison).
So, I guess you're in a real pickle (as we say in the States).
Above 45 mph, the Husky vibrates like a paint shaker on the Tarmac, compared to the Yammie that is smooth as glass.
On the rough trail, the Husky is cat-like nimble with the traction of a bulldozer, compared to the Yammie that feels more sluggish & slower reacting. The WRR is definitely more work in the woods comparatively.....no contest.
In contrast, my (70 degree motor) Husaberg FE390 has all the desirable woods traits, while still running the slab quite smoothly without much vibration.....though I wouldn't want to ride it 200 miles round trip to & from the trail system.
