Its worth what you are prepared to pay
Ive seen similar bikes with less milage go for less here
I paid 6K for a 2011 TB 16K on the clock with a mix of dealer & indie servcing as per schedule - condition wise - mint
It needed new tyres from the off, the originals although having lots of tread, were way past it age wise
ive had it a year, and have just had the 24k service done at 21K
Servicing is a mix of miles and age
So at 6K, 12k (2 year ) 18k, 24K (2 year) i believe
So yours has had PDI , 1st service .5k , then it should be 6k, 12k, 18k & 24k with the 12k & 24k being the 2 year services
Thats a biggy £400+ at an indy
worth it? Absoloutly
I did some rough mileage checks
At worst case it needs a major service
Oil & filter
Air filter
Plugs x4
Belts
Brake fluid change
Gearbox oil change
Rear hub oil change
Valve clearances
I had some additional work & an MOT done , and it cost £420
However i suppled all the OE parts inc new pads F&R & all lubricants which you need to factor in as well
Is it a private or delear sale
