Yamaha Banshee In-Depth Guide

The Yamaha Banshee is a 34 horsepower all-terrain vehicle(ATV) weighing 386 lbs manufactured by Yamaha Motor Company from 1987 until 2006. The Banshee 350 has a respectable top speed of 75 mph in stock condition and an average current classifieds price of between $2000 and $3200 US.

Banshee production stopped in 2006 due to economic conditions but it continued to be sold in Canada until 2008 and in Australia until 2012 as 2006 models. The Yamaha Banshee engine notably does not have an electric starter or reverse gear but is still popular because it is fun to ride. Future Banshee restoration projects will ensure that at least a few Yamaha Banshees survive for a very long time. The Banshee 350 is considered a classic sport ATV by collectors.

Yamaha Banshee Top Speed

The Yamaha Banshee’s top speed is 75 MPH in stock condition. Some owners have recorded runs as high as 85 MPH while others say they can reach 82 MPH in 6th gear in various youtube videos. Weather, altitude, type of gas, engine condition, wind direction and tuning are all variables with an impact. A good baseline as to how fast the Banshee 350 can go stands at roughly 75 MPH stock(without high performance parts).

Yamaha Banshee Oil Capacity and Type

Yamaha Banshee engines are 2-stroke and oil flows through the transmission and clutch. The Banshee requires 1.6 quarts of oil per change. You should always refer to your manual for oil type and amount but if you don’t have a manual you can pick up a Banshee owner’s manual online. Oil capacity is typically stamped on the transmission case but with used ATVs it’s always best to check the manual! There are several brands of oil available, make sure you use “wet clutch” compatible/safe oil that contains no friction modifiers.

Yamaha Banshee Oil Change Procedure

Besides the manual and recommended oil several items are required to make changing your Yamaha Banshee oil simple. These items include a 17mm socket, a torque wrench if you have access to one, an oil funnel, a drain pan and some shop cloth or rags to clean up any spill. Changing the oil on a Yamaha banshee is not difficult, here are the steps:

  • Yamaha Banshee ATV Oil Change Procedure
  • Ride your Banshee to circulate the oil
  • Wipe away any dirt from drain/filler plug area
  • Remove drain plug and let oil drain completely
  • Inspect copper drain plug washer for damage
  • Install drain plug and tighten to 14 ft lbs
  • Insert funnel through filler plug hole
  • Add 1.6 quarts of manual recommended oil
  • Install filler plug and tighten
  • Wipe up any oil spillage imediately

Does Yamaha still make the Banshee?

No, Yamaha ceased production and sale of the Yamaha Banshee in 2006 for economic reasons and increased sport ATV competition. All Yamaha Banshee production has been discontinued indefinitely, however, the market for used Yamaha Banshees for sale remains very strong. It is one of Yamaha’s most popular four wheeler models and has a loyal fan base.
