To provide the highest quality, most reliable products in a timely and
efficient manner so that you are smiling every time you ride your bike.
ENGINES ONLY was started in 1990 By Frank Nye who was prodded by fellow dirt
track riders to make quality big bore kit for the then standard training bike
the Honda XR100.
Our first three motor kits went to Bubba Shobert, Wayne Rainey and Kenny
Roberts. While we still sell most of our parts and motor services to the
professional racing community, our products are designed for use on regular pump
gas and are meant to be reliable, long lasting and stand up to the abuse of
training, trail riding or racing. Our motor components make great torque and
have a wide usable powerband. All of our products are parts that we have
personally ridden and tested for many hours so you can trust them to perform for
ENGINES ONLY continues to develop, test and provide quality products to the
minibike community for Honda, Yamaha, Suzuki and Kawasaki motorcycles. We intend
to bring new and innovative products to production as the industry evolves and
expands with future four stroke minibikes.
