Pipes without a tune can make it run hotter, not faster.

Two guides in one. First, the upgrades. What makes a Harley faster and sound better, and the order to buy the parts in.

Then the rest of what you pay for: tires, insurance, warranties and winter. Harley's own insurance includes just $1,000 for custom parts unless you add more. You find out the day you file a claim.

What's inside

Part One — Pipes, air cleaner and tune

What each one really does, and why the order matters.

Part Two — Stage kits and cams

When they're worth the money, and when they're not.

Part Three — Comfort that pays off

Seat, bars and suspension, for long rides that don't hurt.

Part Four — Tires

What makes them last longer, and how to pay less for them.

Part Five — Insurance

The custom-parts gap, and the discounts riders miss.

Part Six — Warranties and winter

Whether an extended warranty is worth it, and how to store the bike right.

This is for you if:

You're planning upgrades and want to buy each part once
You want lower running costs every year

Skip it if:

You want a full engine build. This guide stops at bolt-on parts.

The honest bit

Keep it street-legal. Some tunes and parts aren't legal on public roads in every state. This guide shows you how to check before you buy.
