Introduction
We at OSSA Motor would like to thank you for purchasing one of
our products.
It is very important that you read this User’s Guide to ensure the
correct functioning and maintenance of your new TR 280i.
As the owner of an OSSA motorcycle, you are the member of an
exclusive group. You have just acquired a unique model, the first
model to be produced since the relaunching of OSSA. The TR
280i is the “visiting card” for our new OSSA Factory. It marks the
comeback, after a 25-year interval, of the legendary brand with
the clover logo, which in the 1960s and 1970s earned itself a
solid international reputation outside the frontiers of the motorcy-
cling world. This is a really special article that will form part of the
history of the brand, of trial racing and of motorcycling as a sport.
The TR 280i is a motorcycle that has been conceived for com-
petition and then adapted to traffic regulations for use on public
roads. It has been specifically designed for trial competitions,
which means that its features are ideal for such conditions. It is
extremely light in weight, both its gears and transmission systems
and the distribution of its component parts have been arranged
with careful attention and make it a revolutionary machine that is
technically extremely advanced.
OSSA motorcycles have been designed, assembled and tested by
experts, and each of its parts has been produced under the su-
pervision of OSSA engineers so as to obtain the best possible re-
sults and the best possible performance.
At OSSA Motor we know that each motorcycle model is unique
and has its own features, which is why we dedicate so much time
to the research and design for each item.

User manual 5
Both your safety and the safety of others are very important when
riding a motorcycle.
Some important advice for using your motorcycle correctly is de-
tailed below.
- Always drive in a responsible way.
- Always use a helmet.
- Never drive over the speed limit.
- Do not ride with passengers.
- This motorcycle is designed to be used in both urban and rural
areas. It should be used, however, while respecting other people
and the environment. If, in your geographical area, the use of
motorcycles in rural areas is restricted, you must respect the law.
- Always wear appropriate clothing and protective accessories.
Gloves, boots and thick trousers, among others, are recommen-
dable. Do not wear baggy clothing that might get caught on a
mechanism in the motorcycle.
- Be careful with the exhaust system! The exhaust system gets
extremely hot during and after use of the motorcycle. In the event
of suffering burns, see a doctor as soon as possible.
- Take the time necessary to become familiar with your new mo-
torcycle.
- Never drive if you have consumed alcohol or any type of subs-
tance (medication, drugs) that might affect your driving capability.
- Make sure your motorcycle is serviced regularly to avoid break-
downs while driving.
- Do not clean the motorcycle with pressurized-water equipment,
since this may damage the parts.
- Do not use your motorcycle for transporting or towing loads. In
the event of needing to carry loads, this load may be light-weight
and small in volume so that driving is not affected. Ensure that
there are no loose leashes or other elements that might get caught
inside a mechanism. Never apply additional weight to the handle-
bars, fork or mudguards. Be specially careful when transporting
any type of load.
