Motorcycle maintenance guides and riding notes from the Technical Tree.
Over 100 million Honda Super Cubs have been built, more than every other motor vehicle ever made. The single design decision that made that possible wasn't about motorcycles at all — it was about carrying noodles one-handed.
The TT has killed roughly 270 riders since 1907 and is still run every year. The reason it still exists isn't recklessness — it's a 1977 downgrade that most people would call a demotion.
That notchy feeling right at dead center, where the bars want to drop into a turn the moment you're off-straight, isn't loose steering. It's dimples worn into the bearing race, and adjustment can't fix it.
Pirsig had a name for the exact moment your hands keep turning a wrench past the point your judgment already told you to stop. It is not a metaphor. It is what actually happens.
Fork oil doesn't just get old, it shears thinner under normal riding, and the shims that shape your damping curve fatigue right along with it. Neither shows up until you already blamed something else.
What plug color and deposit type actually tell you about mixture, oil consumption, and timing — and why most people throw away the diagnosis along with the old plug.
How to measure and set static and rider sag on a motorcycle, and why a stock suspension that "feels harsh" is often just set up wrong for your weight, not actually bad.
Why motorcycle batteries die young, how to actually test one instead of guessing, and the troubleshooting order that saves you from replacing parts that were never broken.
The pre-ride check I actually run, ranked by how often each part has ever caught something real — and the one time skipping the top of the list almost put me in a ditch.
The instinct that ruins slow-speed control: reaching for the throttle to slow down or speed up. Below about 5 mph, the clutch is your fine control and the throttle should barely move at all.
The counterintuitive move behind every tight gymkhana U-turn: fighting the throttle with the rear brake instead of just rolling off. Why creating that "struggle" is more stable than coasting.
Everyone picks the FE 501s over the WR450F for a supermoto build assuming it's the lighter, more exotic option. The spec sheets are lying to you in two different directions, and once you correct for it, the case for the Husqvarna gets a lot weaker.
A WR450F supermoto build, and the one mismatch — master cylinder bore versus caliper piston area — that makes an expensive brake upgrade feel worse than the stock setup it replaced.
The wheel swap gets all the attention in a supermoto conversion. The suspension mismatch that actually makes the bike feel vague on pavement is a damping-character problem, not a spring-rate problem.
Ethanol fuel degradation and parasitic battery draw are the failures that turn a winter of storage into a spring of repairs. Here's the actual mechanism behind both, and the minimum that prevents them.
The tradeoffs between the three ways a motorcycle actually gets power to the rear wheel, and why I still own a chain-drive bike despite everything I just said about maintaining one.
What a worn center strip, chewed shoulders, or one-sided wear actually indicate about your riding, your alignment, and your suspension — and why it's rarely just "the tire wearing out."
Why a top-heavy loaded bike gets genuinely dangerous at low speed, the physics behind it, and the one packing decision that actually affects how the bike handles.
Why brake fluid degrades on a schedule regardless of how it looks, the boiling-point mechanism that makes old fluid dangerous, and how to bleed it properly instead of chasing a spongy lever forever.
How to actually measure chain stretch instead of eyeballing it, and why a crooked rear wheel wrecks tires and handling faster than a worn chain ever will.
Why "snug" and "correctly torqued" are not the same thing, why aluminum oil pans make this worse than it was on your car, and what to actually do once you've already stripped one.
