Wow, not a road you'd ever attempt to carve up but awesome just the same. Fabulous countryside, I'm envious here in flatland Florida. Interesting, a touch of spark knock at the 1:25 mark, has to be the altitude and fuel I'd guess.
The videos dont do the steepness true justice if you understand.
The lakes passes are all awesome and its beautiful country (wordsworth country, you know the i wandered lonley as a cloud bloke).
I have done those passes on all sorts of bikes over the last four decades or so, and i genuinely think, ny XT600E of 20+ years with my XL500s of 17 and 12 years respectively are the best bikes for those passes, with my lowered gear ratio 2003 DRZ400S a close 3rd.
Road bikes i think the torquey tractable 1973 Triumph TR7V 750 tiger was nice in there, and even the XS650 yamahas did it good and i was nearly always two up with her indoors back then too.
good old bikes the XS650 not esspecialy great at anything, but dont fail at much either.
Been up a lot of times on varrious T150/ t150v tridents they never fail to impress me if set up good and fit and healthy they are Real dispite their Trubled British industry Time line.
I think my trials background always pays off when the going gets steep or techy. and these lakes passes are technical in places and catch some riders who should really know better out often. Not bragging here but never failed and closest i ever came was a foot down and bog but no stall thankfully i recovered. it was a jap import early 90s ZX9 streetfighter build of mine with no european carb heaters installed on that import, and it was mid november running like a stuck pig.
Mate bought that ZX9 off me fited some breakers yard carbs uk spec with heaters, and it was a different bike.
all good fun, if any of you visit uk look at the Lakes of you get time its a lovely place, and although touristy in places is wild enough country to offer real remote beauty that area ouses in gallons.
