Kawasaki KX85 Review
KX85 is a dirt bike that does more than leaps. It also hops over the hills. The manufacturer has packed a professional-grade system into this tiny bike to ensure young racers kick off at an excellent level.
Let’s see what KX85 has to offer the kid rider;
Kawasaki KX 85 Top Speed: 80mph (129 Km)
Kawasaki KX 85 Seat Height: 830 mm (32.7 in)
Fuel and Lubrication
Aside from the fuel capacity of 5.68L of unleaded gasoline, KX85 allows switching fuel brands as long as you maintain the standards. But don’t mix and use more than one fuel brand simultaneously, as this may cause severe engine damage.
Also, the single exhaust produces less noise, is lightweight, and is easy to maintain.
As for lubrication, KX85 works well with petrol mix or its equivalent. The oil should have at least API grade or other thickness grades with a favorable temperature.
Kawasaki KX85 awakens through a kickstart method and an electronic Capacitor Discharge Ignition (CDI). The ignition control works at 9 – 12° BTDC at 12,000 RPM.
KX85 features a charging system of the flywheel magneto.
The slim fuel tank and the flat seat allow racers to move freely across the length and at high speed. Also, the clutch uses a pull-type method to ensure flawless operation and easy maintenance. Plus, there are optional spacers to allow quick height adjustments.
Price and Competition
Several dirt bikes are available in the 85cc category to provide you with more options if the KX85 doesn’t excite you. You can choose the RM85, Yamaha YZ85, KTM 85 or Husqvarna TC 85. The competitors’ price range is slightly above the KX85, making it unreachable for most young riders.
