Tomasin Racing T500 Engine Kit for 2026 Husqvarna First Look

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.

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).

The Italian company lists more information about its products and 500cc two-stroke dirt bikes built using Honda, KTM, and Husqvarna platforms on its website, tomasinracing.net.
