A build sheet is a plan with numbers on it.
Unstocked keeps the numbers honest and the plan in an order that survives contact with the paddock.
- 1.1
Select the platform
Pick your bike. Every platform carries a street path and a track path, ordered the way the paddock orders them: protection before power, springs before pipes.
- 1.2
Fill the sheet
Add parts from the catalog or write in your own lines. Typical street prices, a running total, and advisory flags where a part wants a tune or a track.
- 1.3
Hand it over
The finished sheet is one URL and a card image. No account on either end, and anyone who opens it can fork it.
Where does yours start?
Every platform gets the same file: claimed specs, a street path, a track path, category-by-category advice, and the gotchas the forums learned the hard way.
The order is the knowledge.
Thousands of threads and every paddock converge on the same two lists. They differ on purpose: the street buys character and protection, the track buys grip and time.
The street canon
Tail tidy + frame sliders
The day-one pair: fix the tail, protect the bike. Under $350 combined.
Slip-on exhaust
Sound and a few pounds, not power. Be honest about which one you're buying.
Levers + tank grips
Folding pivots survive tip-overs; grips take your weight off your wrists.
ECU flash
The biggest function gain on the list: smooth fueling, factory restrictions gone.
Suspension set for your weight
Sag is free, springs are cheap, and the bike finally rides the way it was drawn.
The track canon
Tires matched to your pace
The only parts touching the track. Too much tire too early is the classic mistake.
Brake pads, lines, fluid
The same lever in session six as in session one, for less than a set of tires.
Suspension sprung for you
Factory settings assume an average rider. Get sprung and set for your own weight.
Make it crash-able
Case covers, rearsets, race glass: a low-side becomes an errand, not an event.
Power, last
Flash before pipe, and only once you're using everything the bike already has.
Real builds, real receipts.
Seed builds from the culture's archetypes: honest totals, honest tradeoffs, and what the builder would do differently.
The broke-college-kid ZX-6R
First season of track days without touching the engine — every dollar goes to not crashing and not running out of tire.
Carbon on carbon: the M 1000 RR
The no-budget M build — full titanium, full carbon, and no pretense that any of it was necessary.
The shed-built SV650
Turn a $1,900 first-gen SV into an honest track bike — suspension money first, engine money never.

Build the sheet once, with your affiliate links and discount codes on the lines. It travels as one URL and a card image, and the codes travel with it.

Torque to spec. Verify fitment. Prices are typical street prices.
