The Yamaha DT125 is the ideal way for the novice rider to make their first steps into the world of off road biking. With its perky 125cc engine, there’s an excellent amount of power to enable the scaling of mountainsides, muddy forests or just your own back yard if you’re lucky enough to have the space. Throttle response is just as you would expect – lively and responsive, enabling those swift starts off the line if you’re looking to take up motocross. With its well-suited tires and forgiving suspension, you’ll also have no trouble tackling the occasional dirt jump or two. So if all these factors aren’t enough of a reason to pick one up, then the DT125’s attractive styling will surely win you over.

Dirt bikes are one of the most difficult, if not the most difficult category of bike to keep out of the repair shop. Why? Purely because of their most common use being found in the most unforgiving and sporadic of environments. With just one false move or awkward landing you could see the end to your tail suspension with ease, so you’ll understand that it’s not the cheapest of hobbies to keep up. The cost in question arises from the price of having your local garage work on the bike, so you’ll be paying through the nose for the labour fee as opposed to the parts, since the DT125 parts are relatively easy to source. But surely there must be a way to learn how to carry out repairs at home?

Well now there is, and all you’ll need to get started is the manual. This is an exclusive guidebook that will help you to remedy any problems you may face with your specific bike and no one else’s. That means that all the information contained within it is relevant and useful, so no more flicking through chapters of general maintenance tips that don’t apply to you. With the Yamaha manual in hand, you’ll quickly pick up the skills and techniques needed to start overhauling your bike after every run. You’ll even have access to instruction on how to carry out repairs of your own accord, so say goodbye to those obscene garage fees.

By keeping up your home maintenance routine and if you plan on owning your dirt bike for a good few years, you’ll save a massive amount of money in this period that would have been lost to your repair fees. Not only this, but you’ll also have a dirt bike that performs at its best every time you ride it, whether that’s once a month or every day. So why not incorporate a home servicing routine into your schedule and reap the rich rewards with the DT125R manual today.
