Kawasaki EX300

The Kawasaki Ninja EX300cc  is based on the Ninja 250R, a lightweight and inexpensive sport bike in production for over three decades.Like the Ninja 250R, it has a full fairing, but a wider rear tire, 140/70, than the instead of 130/70 on the 250R.The Ninja 300 also has 5 spoke wheels, neutral finder, and optional (ABS).By comparison with the 250R, the Ninja 300 also has a slightly smaller fuel tank, taller gearing, and a back-torque-limiting slipper clutch with an assist mechanism that decreases clutch lever effort. Despite being a sport bike, it has comfortable ergonomics (such as mid-position foot controls and an upright seat) which promote commuting.

Performance:

The Kawasaki Ninja EX300cc has a 296 cc (18.1 cu in. ) straight-twin engine Dynamometer tests showed that the Ninja 300 produces more power with 39.95 hp (29.79 kW) compared with the 250’s 25.48 hp (19.00 kW), and higher torque across the rev range at 18 to 13.57 lb⋅ft (24.40 to 18.40 N⋅m).

Its top speed has been recorded at 180 km/h (112 mph) and acceleration at 5.6 seconds from 0 to 97 km/h (0 to 60 mph), and around 14.5 seconds at 141.14 to 145.77 km/h (87.7 to 90.58 mph) in the quarter mile. 

The Ninja 300’s fuel economy was measured at around 70 mpg‑US (3.4 L/100 km; 84 mpg‑imp), while other sources reported it at 54.1 mpg‑US (4.35 L/100 km; 65.0 mpg‑imp), though regardless of the methodology, the 300 showed improved gas mileage over the Ninja 250R.

    Why convert from 520 to 415
    A 520 chain is heavier and larger than a race bike in this class needs. Moving to 415 cuts pitch size, chain mass, and usually sprocket mass with it. That is rotating weight at the countershaft and rear wheel. Extra rotating mass takes more energy to accelerate and throws away horsepower as friction. A 415 chain reduces that loss so more power reaches the ground and the bike picks up revs faster.

    On Ninja 250/300/400/500 KTM 390 and R3 race bikes, a 415 conversion is one of the most effective ways to shed drivetrain weight. The smaller chain also packs tighter, which helps when you are building a dedicated track or Moto3-style machine. Pair the chain with a 415 conversion kit (sprockets and related hardware) for the full weight and friction benefit.
