I actually found one on the net for around £28 in Poland (one in the US was cheaper, but who knows what extras will have to be paid, so....) but the postage was 18 Euros - so in fact more expensive than in the UK.
It's a pretty ridiculous price isn't it - but I suppose we are used to it as bikers, and moreover as UK bikers.
I'm just going to call the guys at Tinklers in Norwich, who have done a Stirling job up to now, of supplying my genuine Yamaha bits with no fuss, and take the hit to my wallet. My baby deserves it, after all, she gives so much and gets little in return.
Ahem...
EDIT: Well there ya go - Tinklers have come good again! The part (part No is 2TK148650100) is £29.66 incl VAT and they charged me 90p postage! Thanks, guys
