Tool advice is usually written by people selling tools. This is the list that actually built the bikes on this site, with the things we bought and never used left out.
Buy these properly
Three categories deserve real money, because failure is either expensive or dangerous.
A socket set. Cheap sockets round off fasteners, and a rounded fastener on an engine case turns a ten-minute job into a weekend. Get a 3/8 drive set in good chrome vanadium with both metric sockets and a decent ratchet.
A torque wrench. Aluminium threads strip at surprisingly low torque and a stripped case thread is a helicoil at best. A click-type 1/4 to 3/8 covering 5 to 60Nm handles almost everything on a motorcycle.
Screwdrivers, specifically JIS. Japanese bikes do not use Phillips. They use JIS, which looks nearly identical and which a Phillips driver will chew out instantly. This is the single most common way people damage a Japanese engine before they have even opened it.
Japanese bikes do not use Phillips screws. They use JIS. A Phillips driver will chew them out, and most people never find out why.
Buy these cheap
Spanners, pliers, hammers, punches, allen keys and files. Budget versions do the job, and if one breaks you replace it for the price of a coffee.
The exception is anything that grips a fastener under load. Cheap circlip pliers are genuinely useless and will fire the circlip across the workshop.
The one nobody lists
A breaker bar. A 400mm 1/2 drive bar costs almost nothing and removes every seized fastener that would otherwise defeat you. It is the most-used tool on our wall by a wide margin.
Do not use a ratchet for this. You will destroy the ratchet mechanism, and a ratchet costs several times what a breaker bar does.
What to skip
An impact driver, until you meet something that refuses to move. A compressor, unless you are painting. Anything sold as a motorcycle-specific tool kit, because they are mostly ordinary tools at a markup.
The thing that is not a tool
A bench vice. It matters more than any power tool you will ever buy, because it is the second pair of hands that lets you do work properly instead of holding a part with your knee.
A 100mm vice bolted to something that does not move is the best 400 zloty in the workshop.
The honest list
| Socket set | 3/8 drive, chrome vanadium, buy properly | 400 zl |
|---|---|---|
| Torque wrench | Click type, 5-60Nm | 280 zl |
| JIS screwdrivers | Not Phillips. This matters | 120 zl |
| Breaker bar | 400mm, 1/2 drive. Most-used tool here | 60 zl |
| Spanner set | Cheap is fine | 120 zl |
| Allen & torx keys | Cheap is fine | 80 zl |
| Circlip pliers | The one cheap-tool exception | 90 zl |
| Bench vice | 100mm, bolted down properly | 400 zl |
| Multimeter | Basic. You will need it for charging faults | 90 zl |
| Total | Everything needed to build a bike | ~1,800 zl |
Common questions
What tools do you need to build a custom motorcycle?
A 3/8 socket set, a torque wrench, JIS screwdrivers, a breaker bar, spanners, allen keys, circlip pliers, a multimeter and a bench vice. That is roughly 1,800 zloty and covers a complete build.
Why do Japanese motorcycles need JIS screwdrivers?
Because they use JIS screws, not Phillips. The two look almost identical but a Phillips driver sits at the wrong angle and chews the head out. It is the most common way people damage fasteners before they even start.
Which motorcycle tools should you buy cheap?
Spanners, pliers, hammers, punches, allen keys and files. The exceptions are sockets, a torque wrench and circlip pliers, where cheap versions round off fasteners or fire parts across the room.
Do you need an impact driver to build a motorcycle?
Not at first. A 400mm breaker bar handles almost every seized fastener for a fraction of the price. Buy the impact driver when you meet something that genuinely will not move.
