It’s a 1.9, but there are (at least) two different versions. Depending on how old it is, you’ll find 80bhp, 105bhp and 115bhp. Ours is 105 and seems to cope OK. Never any problems at all on road, occasionally struggles a bit on forest roads, but that’s often down to wet/loose surfaces. Test-drove a 115bhp version at one point and it definitely had plenty of grunt.
Only annoying thing I find is that the power band is very narrow. Will crawl/stall much below 2000revs and the rev-limiter kicks-in at 3000revs. That really makes the decision to switch from 1st to 2nd on a tricky hill a make or break one!
Which Burtech trailer are you guys using? Braked/unbraked? Did you get them to modify it for “downhill bikes”? Happy with it? Need to get one bought for the summer!
