Do the mods in the right order.
The usual order for street and track, and every guide we've written.
Street and track, in order
Caution:
Pipe before suspension is the classic order mistake.
Street
- Why every forum thread lands on the same list
- The seven mods at a glance
- Steps 1–2: tail tidy and frame sliders, the day-one pair
- Steps 3–4: the slip-on and levers, where the receipts get bigger
- Steps 5–6: tank grips and the flash, the function-per-dollar champions
Track
- The order matters more than the parts
- Tires: the only part that touches the track
- Brakes: real fade resistance for under $450
- Suspension: sprung for your weight, not the brochure
- Ergonomics: rearsets, clip-ons, and the $60 part everyone agrees on
All guides
- 01Do I need a tune? When a motorcycle ECU flash is worth itWhen 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.
- 02The motorcycle fairing shell game: same kit, three pricesMany "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.
- 03Motorcycle levers that don't snap: ASV vs CRG vs PazzoThree 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.
- 04Slip-on vs full system exhaust: what actually changesA 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.
- 05Spotting fake Akrapovič exhausts and counterfeit carbonCounterfeit 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.
- 06The first motorcycle mods, in order: seven for the streetThe first mods most riders make, tail tidy to suspension setup, in the order thousands of threads converged on, with real prices and the steps worth skipping.
- 07Motorcycle suspension first: springs and sag before powerBefore 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.
- 08Track bike prep: what to upgrade, in what orderThe usual track upgrades, in order (tires, brakes, suspension, ergonomics, crash protection, then power) with typical street prices, real failure modes, and what tech inspection actually checks.
