Overview
The Yamaha XT 660R is a dual-sport motorcycle produced from 2004 to 2015. For 2015, it uses a 660 cm³ liquid-cooled, four-stroke single making 47 hp (35 kW) and 60 Nm of torque at 6,100 rpm; wet weight is 181 kg.
An 875 mm seat and 210 mm of ground clearance give the XT 660R a tall riding position suited to uneven routes, though shorter riders may find it harder to put both feet down. The suspension offers 225 mm of front travel and 200 mm at the rear, with spring preload adjustment on the linked rear monoshock; the 15-liter tank sets the fuel capacity for a ride.

Pros and cons
Advantages
Suspension for rough ground
The 225 mm front and 200 mm rear wheel travel help the bike handle uneven surfaces.
Adjustable rear preload
Spring preload adjustment lets the rider adapt the rear suspension to load and riding conditions.
Strong peak torque
The single-cylinder engine produces 60 Nm at 6,100 rpm, giving the rider substantial torque to draw on.
Things to consider
Tall seat
At 875 mm, the seat can make getting on and placing both feet firmly on the ground difficult for shorter riders.
Chain maintenance
The chain final drive needs cleaning and adjustment as it wears.
Weight at low speed
At 181 kg wet, the bike can take more effort to maneuver when moving slowly or pushing it by hand.
