TONI BOU – WORLD TITLE #12

If he hasn’t spent enough time at the top of the trials world, Toni Bou went ahead an won again, wrapping up the FIM X-Trial indoor crown for the 12th consecutive time. Bou, who was coming back from a serious injury, that put him out of action for over a month, could only manage fifth on the night at the Paris X-Trial but it was enough to clinch the world title.

This takes his grand total of World Titles to a massive 23 – really proving he is the GOAT of indoor trials. This short clip from Paris shows the skill it takes to win a World Title.

THE DOWNLOW ON OIL

Oil is one of those subjects that you’d think is as simple as tying your shoelaces. But in reality, there’s a lot more going on with the golden good stuff we put in our engines than at face value.

Unless you’re running an electric bike, your bike’s engine will be filled with oil to lubricate the internal workings. That means pretty much all of us have some exposure to the stuff, but not all of us understand the finer details of oil beyond what the manufacturer of our bike says to put in the filler hole. So what is the deal with oil and why is it a lot more complicated than we give it credit for?

What is oil’s purpose?

Oil isn’t only about lubrication, it’s also there to reduce noise, wear on the engine and even temperature control. That’s a lot of functions for a simple product that looks like golden syrup! With all those differing functions, it is important to keep your oil in tip top shape, so make sure you stick to the recommended oil change frequency to make sure it’s doing its job to the best of its ability.

Those Numbers

One of the first things you’ll notice about a bottle of oil in your local shop is that there are different grades of oil as displayed with a number followed by a W followed by another number. One of the most common grades you’ll see is 10W-40, but what does that mean exactly?

Well, it’s all about viscosity with the first number representing for the oil’s cold viscosity, or how thick the oil is when the engine is cold. The lower the number, the better the cold starting efficiency of the oil is. The W after all stands for Winter. So in theory a 5W oil is better at getting around the oil galleries of your engine on a cold morning than a 10W. But what about the 40? That stands for the viscosity at 100 degrees, as the oil is a multi-grade oil. The reason we get oils with multiple grades is that back in the old days, oil used to come as a single viscosity. This meant that in winter you had to change your oil to a thinner viscosity to aid with cold starts, then change your oil again in summer to keep the oil viscosity within the specs the engine was designed for. What a pain!

 Synthetic, Semi-Synthetic and Mineral Oils

On top of the difference in viscosity, oil also comes in different varieties ranging from mineral oil through to man-made synthetic oil and even varieties that bridge the gap between the two. It’s all confusing stuff, but when it comes to your engine, you only want to put the best stuff in it to keep it going for longer. Generally, (and take this with a pinch of salt) a synthetic oil is the best protection for your engine as all of the molecules are engineered to be the same structure and offer more uniform protection than a mineral oil which has more varying molecular structure. With that said, your bike’s manufacturer will likely have a preferred type of oil with which they have engineered the engine for, so it’s always best to check your owner’s manual before forking out on expensive fully synthetic oil.

Bike Oil vs Car Oil

Even though the viscosity numbers can be identical, you don’t want to cheap out and use a run of the mill car oil in your bike. There are multiple reasons for this, but the most important is that a car oil isn’t designed for an engine that shares its oil with the gearbox. Instead, it is designed to have as little friction as possible in order to increase fuel economy for the heavy four wheelers. Bike oils conversely have less friction modification than a car oil and require balanced friction characteristics between lubricating the wet clutch, which in turn transfers engine power to the drivetrain, and lubricating the rest of the powerplant. So, if you run a car oil in your bike, you will likely find that your clutch is much less effective which will make you slower!

 

OIL FAQs

Is it safe to mix different brands of oil?

In short, it is perfectly safe to mix different brands of oil, the trick is to try and make sure that the oil is of the same viscosity that your engine is designed for. While there are obvious benefits to running one type of oil, if you’ve got to mix and match to get to your destination there’s no major harm in doing so.

Which oil should I use?

How long is a piece of string? Depending on a number of factors we could give a number of answers to this. The safest bet is to pull out your owner’s handbook and read up the section on servicing. Your bike’s engine has been designed with specific tolerances in mind, so best stick to what it was designed for to ensure you get the most life out of your motor.

Should I change my oil more often than the manufacturer’s oil change guidelines?

There’s certainly no harm in changing your oil more often, and in fact racers will change their oil after every meeting to make sure their bike’s engine is getting the maximum out of its oil. If you’re not a racer, you might consider changing your oil more frequently if you do lots of cold starts, high revving city journeys, or even if it has been stored for a while. That last one is important as oil will degrade whether you use your bike or not.

How long can oil be stored for?

Generally an oil manufacturer guarantees oil for three years after manufacture, but some can still retain their oily goodness for up to five. So, if you’re of the sort who likes to do their own oil changes, there’s no harm in stocking up if there’s a good deal on at the local bike shop.

Team NZ 21st in MXoN 2017

SOLID RESULT FROM TEAM NEW ZEALAND IN THE UK

It was a courageous effort, but Team New Zealand could not quite repeat a top-20 result at the weekend’s 71st annual Motocross of Nations in the United Kingdom.

After failing during preliminary qualifying to earn direct entry to Sunday’s main event, the Kiwi trio – Mount Maunganui’s Cody Cooper, Takaka’s Hamish Harwood and Tauranga’s Josiah Natzke – were obliged to race the B Final race first thing on Sunday morning.

This was a “must win” race and, early on, with just two of the three results to be counted, it looked as if they might succeed.

However, even with Natzke finishing third and Harwood seventh, and the Kiwis discarding Cooper’s 14th placing, it wasn’t quite enough to edge out the solid finish of the Slovakian team.

Slovakia was therefore granted a start in Sunday afternoon’s main races (where they eventually finished 19th overall of the 38 nations represented) and Team New Zealand packed up early for the long trip home.

“The word I’d like to use right now you can’t really publish,” said Team New Zealand manager Bevan Weal, of Taupo.

“It’s extremely frustrating, but that’s the way of things with this sport sometimes. It is gut-wrenching to miss out on direct qualification by just one point, Russia outscoring us by just one position on the track. Then to miss out on winning the B Final by just four points from Slovakia … well, it’s depressing.

“It was a case of close but yet so far, and so far away from home too. 

“We had some really good mud riders, but even they were struggling in these conditions today. We’ll be back. Kiwis don’t give up.

 “I want to make a special mention of our sponsors – including Battle of the Clubs, Taupo; Crown Kiwi; Artistic Media and Motorcycling New Zealand – and the whole New Zealand motocross community, without whom we could never have attempted this.”

Team France won the event outright, making it a fourth consecutive year that they have taken away the coveted Chamberlain Trophy.

Runners-up were the men from the Netherlands, with host country Great Britain claiming the third step on the podium.

The Motocross of Nations will be staged at the Red Bud circuit, near Chicago, in the United States next year. 

Final MXoN standings 2017: France 1st; Netherlands 2nd; Great Britain 3rd; Belgium 4th; Switzerland 5th; Australia 6th; Italy 7th; Estonia 8th; USA 9th; Sweden 10th. New Zealand was credited with 21st overall.
