Just got an e-mail from Infinity Motorcycles who apart from mainly being bike gear retailers also sell Yamaha bikes (in London presumably). They are apparently offering a 2013 Unreg Tmax (mk4) for £7412 (a rather odd price).
There again, their website makes no mention of this, and seems to have random prices - it claims that they are selling 2014 Tmax 530 ABS for £7499! If thats true its a bargain!

I suspect it will be true after all you can get a new shape burgman for similar money..

I found mine (new) in August by keeping an eye on MCN's 'Motorcycles for Sale' listings - for rather less than that, I'm glad to say!
