Practical Sportsbikes (UK) - - TRIUMPH TT600 -

1 Swingarm

Fi­nal drive chain slip­per wears through quickly so the swingarm is next to be sawn through.

2 Shock

Of­fer­ings from Nitron and Hagon mean this isn’t a thing to be wor­ried about. Look out for the top shock mount­ing bolt which can rub on the wiring loom if fit­ted the wrong way round. It must go right to left.

3 Ex­haust sys­tem

Head­ers are no longer avail­able from Tri­umph although end-cans still are. Luck­ily there are af­ter­mar­ket op­tions most no­tably from Sprint Man­u­fac­tur­ing and you might still find a NOS sys­tem from Ar­row.

4 Fuel tank

Steel tank does not suf­fer from swelling is­sues of plas­tic tanks on some other Tri­umph mod­els. Dry breaks for the fuel lines can fail. The pipes must be in­stalled the right way round or the bike won’t run.

5 Fuel in­jec­tion

The Sagem sys­tem is dif­fi­cult

to set up prop­erly with­out the use of an af­ter­mar­ket so­lu­tion such as a Power Com­man­der.

6 Throt­tle bod­ies

Air leaks around throt­tle bod­ies which can lead to even rougher low-down run­ning.

7 Camshafts

Changed in Novem­ber 2000 for the 2001 model year in an at­tempt to im­prove low-down run­ning. How­ever the real is­sue was the fuel in­jec­tion.

8 Spark plugs Can seize into the head

be­cause of poor de­sign of the orig­i­nal plug cap/stick coil seals.

9 Oil drain plug

This goes into an in­sub­stan­tial cast boss which is very easy to crack if the drain plug is over­tight­ened.

10 Oil pres­sure switch

Sus­cep­ti­ble to dam­age if bike is dropped on right side and fair­ing is forced onto it. Oil leaks en­sue.

11 Brakes

Nissin calipers are among the best of the era. Float­ing front discs can get rat­tly with wear.
