Build Tamiya's 1/12 Ducati Superleggera V4 with the Racing Kit confidently. Follow a clear order for the Akrapovic exhaust, bodywork, and decals.

Quick answer

Build the Racing Kit version in this order: prepare and test-fit the Racing Kit parts, assemble and install the Akrapovic exhaust, complete the rolling chassis, then paint and decal the bodywork last. This sequence keeps fragile race parts safe and lets you check fit before committing to paint.

Why the Racing Kit changes your build order

Tamiya's 1/12 Ducati Superleggera V4 includes a Racing Kit of parts to make the bike circuit-ready. Those parts, especially the Akrapovic exhaust, clutch cover, and brake lever, are prominent and often fragile. If you assemble the stock bike first and add race parts later, you risk damaging finished surfaces and breaking delicate mounts.

The safe approach is to treat the Racing Kit as the primary build, not an add-on. Test-fit each race part before paint, and keep the bodywork off until the chassis and exhaust are settled.

Where builders usually get stuck

The most common mistake is painting the fairings too early. Racing Kit decals often need to sit over complex curves, and the exhaust and clutch cover must be in place to confirm clearance. Another trap is forcing the Akrapovic exhaust into place before the engine and swingarm are aligned; the joint should close without pressure.

Finally, don't skip a test-fit of the Racing Kit brake lever and clutch cover. These small parts can interfere with nearby details if installed after the surrounding assemblies are glued.

Step-by-step Racing Kit build sequence

Prepare and test-fit Racing Kit parts: Snip the Akrapovic exhaust, clutch cover, and brake lever from the sprues, clean the attachment points, and dry-fit them to the engine and chassis. Do not glue yet. Check that the exhaust header meets the engine port without forcing and that the clutch cover sits flush. If a part needs pressure to fit, stop and check for flash or a misaligned engine half before continuing.
Assemble and install the Akrapovic exhaust: Build the exhaust according to the Racing Kit instructions, then attach it to the engine while the engine is still accessible. Let the joint set before adding the swingarm or rear shock. Support the muffler with tape or a jig while the glue cures. A dry-fit of the rear wheel and swingarm at this stage will reveal whether the exhaust can be removed later without breaking joints.
Complete the rolling chassis: Install the engine into the frame, then add the swingarm, rear shock, forks, and wheels. Keep the front fork and handlebar area loose until you have confirmed the Racing Kit brake lever position. Tighten only after checking that the lever clears the fairing and tank. Set the bike on a flat surface and check that both wheels touch down; adjust the fork height if one end floats.
Paint and decal the bodywork: Paint the fairings, tank, and tail separately. Apply the Racing Kit decals after the clear coat has fully cured. Use a setting solution on curved panels and work from the center outward to push out air bubbles. Let each decal dry before moving to the next panel. Test one small decal on an inconspicuous area first to confirm your setting solution does not attack the paint.
Final assembly and cleanup: Fit the painted bodywork to the completed chassis. Check that the Racing Kit clutch cover and brake lever are still clear of the fairing. Remove any tape residue with a soft cloth and mild cleaner, then display the model on a stand to protect the exhaust. Before shelving, gently rock the bike to confirm the exhaust and bodywork do not touch under slight movement.
