Hi RedRudster
Here is a thread about the Ossa Explorer - http://www.trf.org.uk/forum/viewtopic.php?f=35&t=15780&sid=66b81dea0e4874ff1e7f2dd932728966&start=10
I'm interested in this type of bike for riding long distance trials in the UK. I was thinking about buying one myself but ended up buying the Sherco X-Ride instead because the first year Explorer seemed to have a few reliability issues including gearbox problems, the later versions seem much better. The KTM FreeRide is a similar bike but slightly bigger - not so suitable for trials, the Beta Alp is a bit old fashioned but a useful trials bike as well.
All of these latest generation trail bikes are great fun, light, low and tractable compared to enduro bikes.
Best Regards
