Nice spot. I've cycled up there a few years back (Day 1: I cycled from Glasgow to Killin, via Kilearn, Aberfoyle and Duke's Pass) but not done that route on my motorcycle (Continental GT)...yet.
Good on ya! I see a few cyclists on that route, looks like a tough but fun one. Hahaha "yet". You NEEEEED to get on there with the Continental GT! I tried to do it justice in the video, honestly it's such a good ride.
