Year In Review by Thomas Rendall: Moto Math

thomas r2MOTO MATH

While we all want to be riding on a motocross track more than going to school, I have discovered that math is really a very huge part of the motocross world!

Yes, I prefer motocross to math, but did you know we use it every time we get on our MX bikes?

In the MX season:

Math calculates our overall finishes for the day, series or season points, race entry fees, kilometres travelled, gas, parts and equipment bought or even sold, plus riders and team managers need to know how much they need in parts, sponsorship, and that list is endless. I guess that is why we need to learn super big numbers!

On the MX bike:

Math is used in mixing the gas for my KTM 65 and 85SXSs, or calculating the air/fuel mix in the fuel injected 250/450 bikes for the best performance. We change oil a lot and putting in the right amount is a calculation. We or, if we are lazy, the Factory Connection guys add or subtract to adjust the sag to make our bikes handle best. When doing a top end job we can add or subtract base gaskets to get the right deck height. We count the number of turns in or out all over our bikes. Gear selection for a tight track vs. a long sandy track is all a mathematical calculation to put us ahead of our competition. Dunlop worked the math and came up with even better tires than before with the new MX32 and MX52 tires. My good friends at Nihilo Concepts have used math to make new parts for KTM 50/65/85/105 that are more durable or efficient, and they do a lot of calculating on a CNC machine turning out the amazing parts that are more than just cool looking! A few weeks ago we saw MXP and all the MX sites go crazy with the hype about the New 2015 KTM Factory Edition 450 and the first ever KTM Factory Edition 250. Well, that is all because KTM is pushing the limits and changing to make things even better for riders. I can tell you KTM has a lot of people who know their math!


MX Gear / Equipment:

Companies like Oakley have used math to explain their product features, and to also find ways to design new products like the Airbrake and Mayhem Pro goggles with their injection molded lenses and lens shape. We use math to decide on the number of tear-offs we need in a muddy vs. dry moto, but the Oakley guys used math to make seven tear offs as clear as one with the laminated tear-offs. Now brace yourself because the guys at Atlas Brace have done it again. They have redesigned all the models, but also need to calculate how many they need for each country and not have too many or too little. Bell Helmets started making helmets in 1954. They use math daily in testing and now they offer the Bell Moto 9 Flex to keep us safe! How long have they been making helmets to protect riders? (2014 – 1954 = 60 years). Kutvek Amerika measures number plates, rad shrouds and fenders to calculate the size graphics should be to make our bikes look great.

In MXP magazine:

Chris Pomeroy, Brent Worrall, Bobby Kiniry, and even I have to add and subtract words to make our articles fit a page or part of the magazine, and James Lissimore has to know numbers to take the great pictures. All this can be really hard math!

Oh and yes, there are a lot of ex-motocross racers that work for all these companies in the sport that they thought was just for fun. Now it is how they live in the sport they love (pretty cool jobs right), and they are all pretty good at math I bet.

I did some of my own math at school and here is what I learned about my 2014 MX Season:

I raced from March to December = 9 months
I raced in 58 Races, finished overall 1st – 11x, 2nd- 5x, 3rd -3x, 4th -4x, 5th- 5x, or 19 – Top 3, 28 –Top 5, 40-Top 10, 47 – Top 15
58 races = 130 motos and I finished overall: 1st – 19x, 2nd- 10x, 3rd – 6x, 4th – 9x, 5th- 8x, or 35 – Top 3, 52–Top 5, 80 -Top 10, 49 – Top 15
That equals about 650 racing laps around Canadian and US tracks.

Here are some parts or gear I used:

19           Dunlop MX32 and MX52 tires
10           Grips
4              Alpinestar boots
4              Alias gear sets
2              Bell Moto 9
906         Oakley tear-offs
2              ProTaper bars
10           Twin Air filters
10           Chains and Sprockets

I did this in training and practice:

1058 km on my road and mountain bike
2347 practice laps at MX101, PTF, Bithlo,Waldo, and other MX tracks
40 days in the gym
31 days of kayaking and swimming
15 days of basketball
20 days of cross country skiing

That equals 365 days of fun, with friends and family, and to my surprise I was doing math the whole time!

So if my Math is correct, I should be racing my KTMs again in 3 months!

So when you are sitting on your motocross bike or in math class, remember they both work together!

I wish all of you a Happy and Safe Holiday Season!
