Just idly checking out tyre prices and have found that Crossan Motorcycles are doing Anakee 2 pairs with a £25 cash back to UK addresses (they say that details to claim the cashback will be provided - I'll ring them tomorrow).
So, for the Transalp 650 with 90/90-21 and 120/90-17 tyre sizes that would be £156 less the £25 - £131.
For the 90/90-21 and 130/80-17 that would be £176 less the £25 - £151.
Those prices include delivery to anywhere in the UK and Ireland, by the way. No connection with them other than I am a satisfied customer.
