The manual — ch. 01–08

Read before you spend

The questions every build thread starts with: what each upgrade buys you, which order the money goes in, and which parts only work as a pair.

Ch. 01 — Tune

Do I need a tune? When a motorcycle ECU flash is worth it

When an exhaust or intake actually needs fueling behind it, what a flash really changes, and the cases where the honest answer is to keep your $350.

Ch. 02 — Bodywork

The motorcycle fairing shell game — same kit, three prices

Many "US fairing shops" resell the same Chinese painted-to-order ABS kits at two to three times the factory price — here is what the markup is supposed to buy, how to order direct without getting burned, and when OEM panels or race glass are the smarter spend.

Ch. 03 — Levers

Motorcycle levers that don't snap: ASV vs CRG vs Pazzo

Three shops own the sportbike lever market at $170–$300 a set — here is how ASV, CRG and Pazzo actually differ, what adjustability really buys, when a shorty makes sense, and an honest verdict on the $25 Amazon set.

Ch. 04 — Exhaust

Slip-on vs full system exhaust — what actually changes

A slip-on buys sound and weight, a full system only pays off with a tune — here is the honest math on prices, check-engine lights and legality before you spend $300 or $3,000.

Ch. 05 — Buying

Spotting fake Akrapovič exhausts and counterfeit carbon

Counterfeit Akrapovič pipes and printed "carbon" are now good enough to fool listing photos — here's how to check serials, welds, weave, and sellers before your money leaves.

Ch. 06 — Buying

The first motorcycle mods, in order: the street canon

The first-mods canon — tail tidy to suspension setup — in the order thousands of threads converged on, with real prices and the steps worth skipping.

Ch. 07 — Suspension

Motorcycle suspension first — springs and sag before power

Before the exhaust, before the tune — why springs and sag set for your actual weight do more than any horsepower mod, and how to buy in at $250 or $2,500.

Ch. 08 — Track

Track bike prep: what to upgrade, in what order

The paddock's upgrade canon — tires, brakes, suspension, ergonomics, crash protection, then power — with typical street prices, real failure modes, and what tech inspection actually checks.
