Honda Crf 300 Rx motorcycle service: how to do it, instructions, tutorial

Taking care of your motorbike is the basis on which to build its reliability. If for a road bike maintenance times are extended, in the world of enduro the music changes radically: dust, sand, dirt and fords are constant dangers that require much more frequent interventions. In Desio (MB), at the headquarters of RedMoto – importer and distributor for Italy and Europe of Honda enduro, cross and motard – we carried out a basic service on a Honda Crf 300 Rxwith particular attention also to the protection of the mechanics.

Air filter: the lung of the motorcycle

—

The first operation featured in the video above concerns the air filter: if it is clogged, dusty or dirty, the motorbike breathes poorly and performance drops dramatically, bringing the engine to an “asthmatic” condition. After removing the protective plastic using the quick release and freeing the filter, you need to immerse it in a basin with soap and water (or, better yet, a specific degreaser) to remove any impurities. Once dry, it must be oiled evenly to regenerate the micro-porosities of the fibres. A little professional trick? Spread a thin layer of grease on the edges of the filter before reinserting it: it will ensure a perfect seal against dirt infiltrations. Not only that: another tip is to have a second air filter ready for use so that you never have to give up a ride if the main one is undergoing maintenance. It would be advisable to clean the air filter after each ride, especially if you tackle dusty terrain.

Engine oil: the blood of the engine

Changing the oil is the intervention that most of all guarantees longevity of the engine. The operation must be carried out with a cold engine (woe to do it when hot!). After placing a recovery tray under the motorbike’s engine and removing the drain bolt (usually with a 12 mm socket, but it can vary from motorbike to motorbike), it is good practice to replace the oil filter through the appropriate side opening. Topping up on a racing enduro motorbike can be declared complete once a quantity of oil equal to one liter has been immersed. Used oil, which is highly polluting, must be correctly disposed of. It would be ideal to do this operation every time 5-6 hours of engine use.

Impact protection

—

In enduro, in addition to the internal mechanics, you also need to think about the external ones. Stones, roots and branches can cause costly breakages in the event of a fall or violent impact. During the service it is advisable to install (or check) the engine guard, which protects not only – as the name itself suggests – the engine, but also the frame tubes, especially when tackling the so-called “steps”, real rocky obstacles present in environments where it is possible to tackle extreme enduro. But, more simply, it also protects against branches that can get into delicate areas of the bike, or stones thrown at the engine and frame from the front wheel. It is a simple plastic kit that can be assembled in a few minutes using the holes already pre-drilled on the frame. To this we then added a disc guard for the front disc brake, a solution that is often seen in motocross and less so in enduro. If you are not a professional rider with extremely short technical intervention times on the motorbike, it is good practice to install one in order to protect the brake disc from stones and all the other critical issues that can be found off-road.

from home

—

By doing so, with a few simple operations, the bike maintains a high state of health and is ready for the next outing, all while working comfortably from home. As a corollary, it is good to remember how a clean garage and a well-ordered workstation can make the difference, even for simple operations like these.
