2007 Yamaha DT50R Overview

Yamaha DT50R is an enduro / off-road motorcycle, displacing 50 cc. Power comes from a Single cylinder engine, a compression ratio of 12.0:1. Bore and stroke come in at 40.3 x 39 mm. On the performance side, it delivers 3.30 of torque. On the road, the 2007 DT50R tips the scales at 105 kg, carries a 6-litre fuel tank, offers a seat height of 900 mm and spans a 1,350 mm wheelbase. That's roughly 93.9 kg lighter than the average enduro / off-road motorcycle in our database. The full 2007 Yamaha DT50R spec sheet below covers every technical detail, from suspension travel to tyre sizes.

2007 DT50R - Pros & Cons

Strengths

Factory engineering: Yamaha built the DT50R around a straightforward, purposeful specification rather than chasing any single standout feature.

Considerations

Carburetor fuelling: Expect to spend more time keeping the carbs in tune, especially after long storage periods or a change in altitude.
Tall seat height: At 900 mm, shorter riders will likely be on tiptoes at a standstill - worth sitting on one before you buy.
Modest fuel capacity: Range between stops is limited by the 6-litre tank - plan fuel stops accordingly on longer routes.
Chain final drive upkeep: Budget time for routine chain maintenance - it's cheap to replace but needs consistent attention to avoid premature sprocket wear.

Wear Points & Servicing Notes

Carburetor maintenance

Carburetors on the DT50R need periodic attention - pilot jets and float needles are the first parts to gum up after the bike sits, and the first thing to check if idle or throttle response degrades.

Brake disc and pad wear

Braking up front comes from Single disc - solid stopping power, with disc and pad wear best checked on the same schedule as tyre changes.

Suspension condition on used examples

The DT50R's suspension runs Telescopic fork at the front. The rear uses Hydraulic shock absorber. Fork-seal condition and rear linkage play are the two things worth checking before buying used.

Final drive maintenance

The DT50R uses chain final drive, which is cheap to replace but needs regular cleaning, lubrication and tension checks to get a full service life out of the sprockets.

Low-speed handling

105 kg keeps the DT50R easy to move around in tight spaces, car parks and on the stand alike.

DT50R - Buying & Maintenance Guide

What to check before buying

Before handing over money for a used 2007 Yamaha DT50R, cover the fundamentals: service book and oil change history, chain and sprocket wear, and any sign of oil weeping around the casings. Cold-starting it yourself tells you a lot - a healthy DT50R should catch quickly and settle into a smooth idle.

Oil and filter changes

Nothing protects a DT50R's engine like disciplined oil changes - stay on the manufacturer's schedule (roughly every 6,000 km or annually). Match the viscosity grade to what the owner's manual specifies, not what's cheapest.

Carburetor upkeep

Deposits in the carbs are the usual culprit behind poor running on a stored DT50R - strip and clean the float bowls before the first start. Pilot jets clog first and get overlooked most, so make a point of checking them.
