Yamaha TT-R250 Maintenance Schedule and Service Intervals

2006 Yamaha TT-R250

This is the maintenance schedule and associated service intervals for the Yamaha TT-R250.

Yamaha made the TT-R250 from the mid-nineties (depending on where you’re from) to 2006 and left it pretty much unchanged in this period. It was the first mainstream trailbike with electric start!

Surprisingly, people didn’t really trust electric start back then. But it soon won everyone over.

About the Yamaha TT-R250

The Yamaha TT-R250 is an entry-level trail bike that Yamaha produced from 1999-2006 to compete with the Honda XR250R.

The TT-R250, like other motorcycles in its class, was powered by a single-cylinder thumper engine. The TT-R250’s engine was a 249cc DOHC air-cooled four-stroke carburettor-fed engine that made 21 kW or 28 hp at an impressive 8,500 rpm, or 27 Nm/20 ft-lb of torque @ 7,000 rpm. Quite a high-revving single! It put power down through a 6-speed transmission and chain drive.

The TTR250 was equipped with electric start, and was designed to be reliable and long-lived. These are rock-solid all-day trail and dirt road bikes that will plug along (like a tractor, as one poster put it) or pull right up with the pack. It’s capable of doing some time on the highway but obviously, this is no Road King… it’ll take you to nearly 120 km/h, but you’ll need the wind behind you to go any faster.

The rear disc, stronger engine and better suspension puts it way ahead of the 230s and lighter trail bikes.

Technology on the TT-R250 is deliberately very simple. It has a Teikei slide carb that can be stripped out and cleaned easily, a cable-operated clutch, but still has a four-valve head with a self-tensioning cam chain.

The engine in the TT-R250 has a broad spread of power, with lots of torque even from down low.
