Hi although honda recommend checking every 16000 miles my own experience with st11 and st1300 of which i usally covered 150,000 miles + i found on 5 st versions i only had to change very few shims, thought out the miles , worth checking yourself every 16-20,000 miles especially 1st time round as the bike beds in you may need to change a few initially, but i wouldn't waste money having your dealer do them every 16000 miles, unless that mileage takes you years, then the price dosent really matter, most important items on the st range is regular oil/filter changes, and if it becomes thirsty or sluggish, plugs and air filter, apart from that and pads/tyres etc these st v4 engines are ideal for lazy or poor riders,as you dont need to spend a fortune, but again your average rider wont mind putting it in the dealer every year, i usally have the 1st 2 services done upto 8000 miles then self service,but i can do 30-50000 miles a year .. if the new bike has any issues it normally shows after 6-10,000 miles, but i havent had a bad v4 st yet? anyway just my own experience, but if you change bikes regularly on low mileage ill always say best to get it dealer serviced and stamped for the top re sale etc, but at my mileage its not a issue..ride safe cheers Garry, and im not a really convinced that most dealers care for your bike as much as you do!
