The OSET 20 motor is an all new OSET design using the very best internal components and paying special
attention to performance and reliability. Over 50 individual components go into the motor, with most
specially designed to best suit our goals. A lot of attention was paid to important details, like waterproofing,
brush size, wire and bearing quality. Items all the way down to brush springs were specifically
designed to meet OSET’s standards. Every part was carefully considered.
Better by design...
OSET 20.0 controller is a work of art if you appreciate circuitry and electronic engineering! This is NOT
a standard ‘off the shelf’ controller. It features a very stable high output MOSFET structure with ground up
component and circuit board design. This controller will reliably output a huge 100 amps (OSET 12.5 &
16.0’s have a 40 amp output). High output means high performance. This controller was designed in
conjunction with the OSET motor, so they work perfectly in unison. The true beauty of this controller is the
ability to change the performance with the push of a button and twist of a dial (located under the rubber
‘bung’ in the tank) in seconds. The settings will allow the bike to be set almost instantly for different riders
and conditions. Novice riders can set for a slower speed and easier response. For muddy conditions, the
controls allow the bike to be set to respond very smoothly. Months of testing have resulted in controls
that allow the bike to respond for an expert or a novice, or anyone in between!
FRONT: The OSET 20.0 front fork is a high end 100mm travel ‘AIR’ fork allowing an amazing level of adjustment.
Firstly, the air ‘spring’ is infinitely adjustable with changes of pressure. In addition, a multi-position
rebound dial allows a great range of rebound rate changes. This fork features an aluminium steerer and
crown and magnesium lowers. The big 36mm stanchions provide great stiffness and rigidity as does the
20mm through axle.
REAR: The rear suspension is also adjustable for rebound with a simple dial, as well as pre-load. Each OSET
comes standard with a 650lb spring, with an optional 1000lb spring in the box for heavier riders. There are
two lower shock positions available allowing additional alterations for travel and feel
A great bike needs great brakes. The OSET 20.0 features strong hydraulic
brakes with reach adjustable levers. Hydraulic brakes offer much
more power than mechanical brakes, while at the same time requiring
less force on the lever. The front disc is protected by our OSET designed
disc guard, as required by regulations for some competitions.
And there’s more...
The hubs used on our smaller OSET’s are not adequate for the OSET 20.0. We custom made our OSET rear hub with high quality sealed bearings and a ‘bolt’ system on both sides for the disc and the rear sprocket A standard hub would eventually cause problems. Our new OSET hub is unique and exclusive. The front hub uses a 20mm through axle for maximum strength and the most stable ride.
The OSET 20.0 foot pegs are designed with our youth riders in mind. These light weight alloy pegs feature rounded teeth and a solid platform. The mount system is unique in allowing 2 positions, so they can be ergonomically optimized for different size riders.
We wanted super smooth rear suspension movement, so the swingarm rides on 2
bearings on each side.
