Hi Rik. I can fully understand your disappointment with these hassles with your new pride and joy. It sounds like your main dealer (Blade Triumph?) are at least doing as much as they realistically can at present to restore your faith in the bike and the brand. Problems like these can occur on any mechanical device and they are, of course, utterly frustrating when you've paid a LOT of money for a premium product that doesn't seem quite so premium when it fails!
I'm hoping that you'll come back on in a couple of days time and say that everything's fixed, the sun is shining, the roads are dry and the Cotswolds are a great place to demonstrate the pleasures of owing and riding a Street Triple!!
