Several lads used them on the Moor to Sea, the 2T sounds very trially engine wise, was quite impressed.
Wasnt overly impressed with the 4T, seem to have been several issues.
I've had a 4T since April, it was a hardly used 2012 model with 200 miles on the clock, and have put 900 miles on it without any issues apart from the pitifully small fuel tank. I find it rides like a trials bike in the lanes but with better suspension than a trials bike to soak up bumps at speed. After all, trials bikes are not designed for speed.
