Here’s some more pics GB
The A10 is pretty good on gravel (narrow tyres help) but the bumps can be very hard on the old bikes, and you really should have a top class air filter due to the dust. You can drop the KTM and probably not get much damage, if any, not so the old bikes.
I do sometimes use my B44 for the shorter gravel rides, but that still seems a bit cruel! It’s only got a couple of inches of rear suspension travel, vs around 9” on the KTM
Odd thing is with the prices of old bikes, I reckon my B44 is probably worth more than my KTM, and my A10 definitely is worth more.
Basically one needs many bikes, one for each purpose (try explaining that to “mission control” eh)
