Yes, its another which tyre is right for me question, which i realise straight up its extremely dependant on riding style, weight on the bike, road surface, all that... Im after the opinion of people who have used the tyres in the list below on either the same or similar style of bike in what id call general riding - some commuting, some two up, some solo twisties riding... Its a 2009 Triumph Sprint ST. Stock tyre sizes are front 120/70x17, rear 180/55x17. Based on reviews elsewhere, im rather spoilt for choice between 3 sets that meet my general criteria of good in all weathers, good wear characteristics, and good kms in general riding... Michelin Power Pure. Avon Storm ST. Metzler Roadtec Z6. All these come in between $450 and $550 for a pair. The power pures are the lightest tyre, and seem the best for the dual compound setup ive read about so far as a wide soft compound on the tyres shoulders. The storm sts are reportedly the best wearing, at 12000km from a front and 6000+ from a rear with plenty of hard riding - far and above the best distance. Z6s are somewhere between those two from what i understand of it, and ive experienced how good they are on the old boys beamer in the wet heading down to wisemans ferry. Ta!
