Paint codes are not recorded. Replica kits are decals, not a different engine. The frame polish and the livery list are.

Before you start

Paint, polish and decals

  • A replica is stickers, not a different engine.
  • Chesterfield is not a sourced 1998 scheme.
  • There is no paint-code table on this page.

How many steps: 6

Tools

  • The polish you have checked is meant for bare aluminium, if the frame is bare
  • Masking materials and a panel wipe. The product is your choice; none is specified in the brief.
  • A warm, dust-light place for decals. Temperature range is To verify on the kit’s own sheet.
  • The year’s scheme beside you, from a sourced gallery, not from memory of a race weekend
  • Photos of the bike before the old stickers come off, so you can put a non-replica bike back as it was

Parts

  • A decal set matched to the year and the bodywork. Decalmoto is the supplier named in the brief.
  • Paint mixed to a code you have sourced. No codes are printed here.
  • Clear coat and primer suited to the plastic. The system is To verify with the paint supplier.

Slots for these parts, with empty OEM numbers and empty prices, are in theparts directory.

Replica table in the research brief

Paint is the slow part, and it is the part this site will not fake. There is no paint-code table, because the brief does not contain one. There is a livery list, a rule about what a replica is, and a warning about the 1998 Chesterfield.

A replica is stickers

Hartrusion, via the brief, is plain about it. “Replica” means the decal scheme. The engine, the carburettor and the restriction are whatever that year and that model code left the factory with, plus whatever an owner has changed since. A Rossi kit on a restricted MPA does not make it a factory open bike. A Chesterfield kit on a GS does not make it a 1994 if the frame number says otherwise.

Decalmoto is the kit supplier named in the brief, with sets by year, roughly €95 to €140. That range is in euros. It is not a sterling price and it is not an affiliate link. To verify the current price on the day, in the currency you will actually pay, and write it in the parts directory with the date if you are keeping a record. The directory on this site still has an empty price on purpose.

Match the kit to the body. A 1998 Rossi set belongs on the round-light fairing. A 1999 Rossi set belongs on the bee-tail. The colours can look similar in a thumbnail and sit on completely different panel shapes.

The 1998 question

The Rossi replica is a documented 1998 livery. A Chesterfield scheme is not, on the sources in the brief. Chesterfield is 1994 on the Extrema, Biaggi Chesterfield is 1995–96, and Chesterfield is a bee-tail scheme from 1999 to 2005. Before any paint is mixed, decide whether you are restoring a 1998 scheme that the sources have missed, or repainting a bike into a year it is not. To verify with the frame number, the engine and the date of first registration. The full check is on the identify page.

Loris Capirossi is named in passing in one magazine piece and is not verified. Do not paint a bike as a Capirossi replica from this site.

Polish

Polished frames start as a 1994 Telaio Lucido and, in the brief, as the general finish from about 1995. The earlier GS frame was painted silver. Read guide 2 before you cut a finish back. Polish is for oxidation and light marks. It is not for a crack, and it is not for a casting flaw you have decided to “blend”. Stop at the edge of any weld. The compound is To verify against a product meant for bare aluminium.

Paint

Take the code from a chart or from a panel that is still original, scanned by a paint shop. Both routes are outside this brief, so the code on your tin should be one you can point at. Plastic panels need a flexible system. The brand is To verify with the supplier. Repair cracks before paint, or the paint will map them.

Decals go onto clean, fully cured paint. Follow the sheet in the kit for water, heat and the order of the layers. That sheet is the procedure. This page will not replace it with a guessed sequence. Photograph the finished bike in daylight. It is the “after” half of the condition report, and it is how the next owner knows the stickers are a kit rather than forty-year-old factory glue.

Common mistakes

  • Buying a Chesterfield kit for a 1998 bike because the owner calls it a Chesterfield. The sourced schemes are 1994, 1995–96 Biaggi, and 1999–2005.
  • Polishing through the edges of a weld.
  • Assuming a replica kit changes the carburettor or the power.
  • Fitting a round-light sticker set onto a bee-tail because the colours match.
  • Painting a cracked panel and expecting the crack to stay shut.
