The starting point is to differentiate between the two prominent battery chemistries used for motorcycles, and how they generate electricity.
Lead-acid (Pb)
This includes AGM (Advance Glass Mat), MF (Maintenance Free) and Gel, all of which contain lead plates and diluted sulphuric acid (AKA electrolyte). Power is generated through a chemical reaction at the surface of the plates, but two other things happen as a result. Lead-sulphate is produced and the electrolyte loses acidity (weakens).
Sulphate binds with the lead plates to form a soft snowflakelike crystal, called lead-sulphate. When the bike's engine is running, the battery recharges and the electricity flowing in reverses the chemical process, breaking up the lead-sulphate. This returns to the electrolyte and increases the acidity.
Providing your motorcycle is ridden regularly, for a reasonable amount of time and at highway speeds, things should be fine. However, if your bike is parked up for several days, weeks or even months at a time, it will gradually self-discharge, producing lead-sulphate. Over time, the sulphate will harden on the lead plates and eventually create a barrier, which stops the weakened electrolyte from reacting with the lead. At which point the battery is dead.
Since a fully-charged battery has no lead-sulphate, using a basic charger-maintainer, like the OptiMate 1 Duo, will top up anything lost through selfdischarge. Simply connect to the battery when the bike is stored and it will automatically do the rest.

Highway to Heaven
Three friends take on the challenge of riding the length of Canada, from Vancouver in the southwest to Inuvik in the north. The road is long, the conditions merciless, and wildfires are tearing through the country. To top it all off, the final leg of the journey is the ultimate test of gravel riding skills, nerves, and courage - it's the legendary Dempster Highway...
Battlaxes at the ready!
We tend to take tyres for granted, never really looking at them in any detail, or at how they work, just hoping that they keep us shiny side up at all times. Even in the wet
Ducati Riding Experience
When I rode the Ducati DesertX to France last year, I did have a bit of an explore on some easy fire roads and gentle green lanes in the wilds of the Médoc area, but was left with the feeling that, had I the experience, the DesertX would have been capable of taking me along some more extreme trails to some even more exciting places. If only there was a way of finding out just how well the Italian adventure bike could cope with some more extreme terrain...

Many said that sports bikes, and particularly bikes in the traditional Supersports class that was populated by 600cc inline fours, were dead. Maybe they spoke too soon?...

First Time Lucky?
It's ironic that the first all-new MV Agusta model to hit the marketplace right after Italy's No.1 trophy brand was acquired by Austrian giant Pierer Mobility, owner of off-road titans KTM, should be the company's first dual-purpose model of the modern era, powered by MV's all-new 931cc three-cylinder engine that's destined to form the basis of a whole series of new models in coming months and years.
