The 2021 T100 received an updated 900 cc twin, Euro 5 compliant with roughly 10 PS more than before and a higher rev limit, plus lighter internals saving about 4 kg. It gained a Brembo front brake, upgraded cartridge forks, new twin shocks and 32-spoke wheels. A new instrument face and LED rear light completed the changes.
