I had my 20,000 service at Triumph Newcastle.
Service 2 shims and fitted two new tyres:
Labour £312
Parts, Oil, Service Kit, two Michelin PR4GT, 2 shims and set brake Pads £440.48
VAT £150.50
Total £902.98
Since then I have bought and fitted a pair of PR4GT's and saved about £70 on the above prices.
I think their prices are on the high side but it is convenient for me and I was kept informed and bike felt great after this investment.
