Surface Guard Tape
July 4th, 2008 · No Comments · Technology, Vintage
Here’s an interesting product I came across recently from ISC Racers Tape — Surface Guard Tape. According to the company it’s “a bullet-proof, 8 mil clear, urethane paint protection tape. You cannot puncture this tape with a pen.” It has a semi-permanent adhesive and protects against UV, extreme temperatures, and automotive solvents.
I’ve been using a [...]

Michael Scott’s “In The Paddock” column in the new Cycle News, (pg 60, July 2, 2008) is all about the two-stroke motorcycle engine, its past, present, and future. Some interesting stuff there. Mostly Scott talks about road racing and the death of the 250 GP class, which DORNA has killed effective 2010. But he also [...]

Big balls, American style. MotoCzysz C1.
June 22nd, 2008 · No Comments · Technology
I’ve been watching a two-hour documentary from Discovery Channel on MotoCzysz (pronounced moto-siz), the 100% American-made, from scratch, MotoGP machine. Yes, you read that right – one dude from Portland, OR (who isn’t even an engineer) decided he could take on the world and build a world-class MotoGP prototype racing machine from scratch. It’s taken [...]

Why has only one company successfully entered the MX market since 1985?
June 3rd, 2008 · 2 Comments · Technology
To my knowledge only one (1) company has successfully entered the motocross market since 1985 – the small Hillsdale, MI firm of Cobra Motorcycle Mfg. What did Cobra do? They brought innovation to a market the Big Four were ignoring. They met a need. They built good products – right here in the USA.
Once – [...]

Fairytales and Myths About Modern Racing
March 16th, 2008 · No Comments · Industry, Technology
I just saw a boisterous rebuttal of an earlier article – The Long-term Effects of Production-based Racing – over on the TMSuzuki Yahoo! group. I can’t post it here because I don’t have permission but I hope the author will stop by and do it himself. The author takes great exception to my assertion that [...]

According to Don, the response to his appearance on “The New Inventors” (which named the cone-head 2007 Invention of the Year) has been huge, with interest from around the globe. A helmet using [...]

Which Helmet Is Safest?
March 2nd, 2008 · 1 Comment · Safety, Technology
Looking at the new Bell Moto-8 got me to thinking again about the controversial issue of helmets. Mainly because the Moto-8 is at the higher end of the price range for motorcycle helmets, and there is really no objective way of determining if your money is truly buying you more protection. In a non-scientific survey [...]

Protective Gear From Indy – RC-Evolution, Shock Doctor, Moto-8
March 2nd, 2008 · No Comments · Safety, Technology
There were a handful of new safety products announced at Indy. I didn’t see them all but I did get a chance to see a couple of them up close and talk to the manufacturers. EVS Sports announced their RC-Evolution Race Collar, a less expensive competitor to the Leatt Brace. The RC-Evo is similar in design to [...]

Getting Un-KREEMed
January 2nd, 2008 · No Comments · Technology, Vintage
I have a very nice, low-hour 1974 Yamaha TY250 trials bike. I bought it last year and it’s in good shape but has two issues I need to fix – it leaks oil from the bottom of the motor somewhere, and the fuel tank is full of crap that keeps clogging the petcock. We’re going [...]
