What is due at 25000 miles? - Trident 900 Triumph Motorcycles

Normally if you have been following your Owners Manual, it would tell you what need to be done every 200 miles (or weekly), 600 miles (or monthly), 2000 miles (or quarterly) and 4000 miles (bi-annually).
Generally, most important is doing oil and filter change every 2000-2500 miles (quatertly) and if you have fuel filter installed to ensure it is clean and free-flowing. Air filter need to be changed depending on your travelling conditions, rule of thumb speaks every year in the spring if your live in a 4 season or every 6 months in a 2 season element weather.Tightening and adjusting all nut, bolts and valve clearances as required, drain beather hose (must be done quarterly), adjust chain-tensioner, clutch, spark plugs gap, inspect brake hydraulics functions, pad thickness and liquids (a good idea is to change brake fluids every year), check electrical systems functions, suspension, wheel-bearings, steering linkages,suspensions, etc. If your bikes shakes at 50 - 60 mph then get your wheels immediately balanced as this will create a bigger headaches if not attended. Good luck and if comment is helpful then return 4 thumbs up.
