Stay Cool!
Back in the seventies, we didn’t have mesh jackets and the riding gear that allowed us to ride in intense heat and stay fairly comfortable as we do now.
Plus we were ignorant of how to handle heat with the clothing we had available to us.
We rode a lot in high heat situations and , looking back, boy were we dumb. We would ride in just t-shirts and sometimes no shirts at all. We rode without helmets and yes there was no helmet law then. We were simply trying to not allow the heat to get to us. It didn’t work and we were miserable on a lot of those rides.
I remember the club was on a long ride through the desert and we would stop about every half hour to drench our t-shirts and hair in ice water, from the coolers in the back up truck, then get back on the bikes and ride. A half hour later we were completely dry and very hot again!
We are blessed now with Helmets, jackets, gloves and whole riding suits that have great ventilation and can keep you reasonably comfortable in very hot conditions.
If you are going to ride in very hot conditions do some research on hydration, your gear’s ventilation and how your body reacts to heat. There is so much information at your fingertips!
Speculations on Triumph’s 250 Motocross Engine
What can we tell from the latest teaser?
In accordance with established Internet marketing principles, Triumph has revealed a few details and photos of its new four-stroke 250 motocross engine, with broad hinting that it will in time serve in other roles.
As some have already commented, its general appearance is like that of the current KTM 250, with forward-facing exhaust, primary drive on the right, and chain-driven DOHC. Also like the KTM the crankshaft’s primary pinion also drives a jackshaft directly above it, where the 2:1 reduction for the cams occurs. The water pump is on the outer end of this shaft.
This produces some confusion, as with the bottom cam-chain sprocket turning opposite to the crank, the cam-chain tensioner is now on the front of the chain housing, giving the initial (but false) impression that the engine spins opposite to the wheels—in the case of Yamaha’s first M1 990cc MotoGP engine of 2002, the tensioners being on the front gave correct information—that engine did spin opposite to the wheels.
