2024 Trek Speed Concert SLR 9 Triathlon bike

Description

2016 Honda® CRF®250X Canadian trail-ready. Features May Include Engine & Drivetrain Easy-control operation Powerful 4-stroke 249 cc liquid-cooled four-valve Unicam engine is designed to produce power across a wide rpm band for easy-to-control operation. Unicam valve train provides the light weight of a compact single-cam design and the optimum combustion chamber shape for maximum power at all engine rpm. Incredibly light weight Unicam valve train features a carburized single camshaft that directly actuates two 31 mm titanium intake valves. The camshaft exhaust lobe actuates two 26 mm steel exhaust valves via a forked, low-friction, roller rocker-arm. Lightweight titanium intake valves permit use of smaller valve springs, reducing overall engine height. Vertically split crankcases feature a built-in oil pump, reducing weight compared to a conventional design. Performance & durability Double-carburized connecting rod utilizes a big-end needle bearing for maximum high-rpm performance and durability. Nikasil cylinder lining is lightweight and provides cooler and quieter operation for extended engine life. Eliminates contamination Twin-sump lubrication system separates the oil supply for the crankshaft, piston and valve train from the clutch and transmission. This ensures a cool supply of oil to the clutch, eliminates clutch and transmission material contamination of the engine oil, reduces the amount of circulating oil, and permits the use of a smaller oil pump. Chassis & Suspension Comfortable manoeuvrability Semi-double-cradle twin-spar aluminum frame features a single large-diameter tapered downtube. Two rugged box-section rails attach to the base of the downtube and support the engine. A forged aluminum steering head provides a compact and extremely durable mount for the frame spars and engine downtube. In addition, tall swingarm pivot plates and narrow frame spars create a narrow overall frame cross-section for superb rider comfort and manoeuvrability. Swingarm features a dual-axis, double-taper design with a large cast-aluminum cross-member. Low-friction operation Lightweight 47 mm inverted Showa twin-chamber cartridge fork with aluminum dampers is derived from the CRF® 250R and features settings unique to the CRF® 250X. The fork offers 315 mm (12.4 inches) of travel, and 16-position rebound and 16-position compression damping adjustability. The inner surface of the front fork outer-tubes receives the same honing treatment as works bikes for low-friction operation. Handles all situations Pro-Link single-shock rear suspension system features a fully adjustable Showa rear damper and 313 mm (12.3 inches) of wheel travel, separate low-speed (13 positions) and high-speed (3.5 turns) compression damping adjusters, and 17-position rebound damping adjustment. Additional Features Increased rider mobility Seat cushion uses foam construction that follows the shape of the fuel tank, providing a smooth transition to increase rider mobility and c
