Tomasin Racing T500 Engine Kit for 2026 Husqvarna First Look

Turn your 2023–2026 Husqvarna FC 450 or 2023–2024 FX 450 into a TC 500 or TX 500 with this product.

The TC 300 lasted only one year as a production model in Husqvarna’s lineup, and that was 2025. Now, the Austrian brand’s largest-displacement two-stroke motocross bike is the TC 250. But what if you could double its displacement and create a TC 500? It’s possible with Tomasin Racing’s T500 Engine Kit, which makes use of Husqvarna’s 2023–2026 FC 450 and 2023–2024 FX 450 model platforms.

Husqvarna doesn’t produce a 500cc two-stroke dirt bike, but Tomasin Racing can turn select 450cc four-stroke motocross and cross-country models from the Austrian brand into one with its T500 Engine Kit, which retails for 8500 euros ($9963) without gearbox.Tomasin Racing

When purchasing the T500 Engine Kit for Husqvarna four-stroke motocross and cross-country racers to turn them into a 500cc two-stroke, the original crankcase, primary gears, starter motor gears, flywheel, stator, and complete clutch are needed. Cost without gearbox is 8500 euros ($9963). Those interested in an electric start-equipped fuel-injected 500cc two-stroke Husqvarna motocross bike can also buy one from Tomasin Racing for 17,500 euros ($20,511).

Instead of buying a 2026 Husqvarna FC 450 and T500 Engine Kit separately, Tomasin Racing sells those products as a complete ready-to-ride package for 17,500 euros ($20,511).Tomasin Racing
