Introduction
On behalf of OSSA Motor we would like to thank you for having
purchased one of our products.
As the owner of an OSSA motorcycle, you form part of an exclusive
group: you have just acquired a unique model, the first of OSSA’s
re-launch. The TR 280i is the OSSA factory’s new presentation
catalogue. It represents a return, after twenty-five years, of the
legendary clover brand. In the 60s and 70s, this brand received
extensive international recognition that went far beyond the world
of motorcycling.
The new OSSA motorcycle belongs to the first series, a production
batch of only 1,250 motorcycles. These bikes will be distributed
both nationally and internationally. It is, therefore, a genuinely
special product that is destined to go down in the history of the
brand and in the history of trial riding and motorcycling.
The TR 280i is designed for competition riding but is also adapted
to traffic regulations for use on public roads. This motorcycle is
designed for motorcycle trials, comprising the best features for this
purpose: it is extremely light-weight and the gears and transmis-
sion are very precise. All of this in addition to the distribution of its
components makes the motorcycle a technically advanced and
cutting edge product.
OSSA motorcycles have been designed, assembled and tested by
experts and all parts have been manufactured under the supervi-
sion of OSSA engineers. This ensures that top-of-the-range motor-
cycles are guaranteed.
At OSSA Motor we know that each motorcycle model is unique with
its own specific features. For this reason, we spend a lot of time on
the research and design phase for each part and for each model.
It is important that you read this manual thoroughly in order to keep
your new TR 280i in full working condition.
* Model without standardisation kit

Safety
Both your safety and the safety of others are very important when
riding a motorcycle.
Some important advice for using your motorcycle correctly is
detailed 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 recommenda-
ble. Do not wear baggy clothing that might get caught on a mecha-
nism 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 motor-
cycle.
- Never drive if you have consumed alcohol or any type of substan-
ce (medication, drugs) that might affect your driving capability.
- Make sure your motorcycle is serviced regularly to avoid break-
downs while driving.
- Do not use your motorcycle for transporting or towing loads. In the
event of needing to carry loads, make sure that they are
light-weight and small in volume so that driving is not affected.
Ensure that there are no loose leads or other elements that might
get caught inside a mechanism. Never apply additional weight to
the handlebars, fork or mudguards. Be especially careful when
transporting any type of load.
