LF AVENGER<sup>®</sup>


Since 1953, unsurpassed quality, safety and innovation has kept Champion® a market leader in the midsize commercial bus industry. The Champion® Avenger® is no exception with its unparalleled accessibility and smooth comfort. It boasts low floor accessibility, a bi-fold ramp, and kneeling feature in order to give your passengers the convenient approachability they need. It adds innovative options like the OverRise ™ feature that lifts the entire vehicle up to 2.5 inches higher than the OEM ride height at the push of a button, the only bi-fold ramp available today that can exceed the new guidelines at EVERY stop.  Matched with its spacious interior and effortless ride, the Avenger has it all.



All Champion buses are created with the passengers in mind. That’s why the Avenger is spacious and highly customizable to accommodate a variety of seat-to-wheelchair ratios, luggage options, fabric, lighting types, cab controls, window preferences and more.  The spacious interior of this low-floor bus has 102”wide floors allowing for plenty of room to meet ADA compliance and is consciously flat to make it even easier to move around.



The Champion Avenger’s most notable features are the large passenger and passenger-side cab windows that allow for maximum visibility for both the riders and the driver. The sleek exterior body is also equipped with single-step entry with no lifts for better accessibility. There are a variety of graphics packages and paint schemes available to deliver the perfect look for your application.
