Difference between revisions of "Yamaha TZ250"

The '''TZ250F''' heralded welcome news for Yamaha fans when it was released in 1979. A 11kg weight reduction was achieved through further changes to the frame, (despite the fact they reverted back to welded steel engine mounting brackets from the alloy ones on the "E") including a steeper rake and an alloy swingarm, as well as this the bike featured a new exhaust and mounting system, an additional o-ring (from the previous single o-ring) in the header pipe, new conrod, wider intake port and minor carburettor mods.  The primary drive gear picked up 2 teeth to match the 350's 25, the cylinder drain tube was altered. A dipstick was also introduced and the brake [[caliper]]s became cast alloy units like the 750's . Power remained the same as it had since the "D" at 53bhp @ 10,500rpm.  A new fairing adorned the machine which was pointed below the header pipes and eliminated the old aluminium belly pan, a new fuel tank and seat unit appeared, and the clutch cover was reduced in size to a pressed aluminium job (the previous models utilised a cast aluminium unit completely covering the clutch) surrounding just the rear of the clutch unit.
