For 2021 KTM and Husqvarna have launched apps to complement their motocross ranges. In the case of Husky, the app needs a Connectivity Unit to be mounted on the machine and this is available for all MY21 four-stroke models and can also be retro-fittted to the 2020 FC450 Rockstar edition. In addition to the Prime and Advanced engine modes, the app gives recommendations for the optimum suspension settings.
KTM goes down a similar route with a bar-pad integrated Connectivity Unit. Working with the myKTM app, the power characteristics of the SX-F range can be personalised for riding styles and track conditions without technical assistance.
SX update
The KTM two-stroke SX range, in 125, 150 and 250cc guises, gets an improved power-to-weight ratio for 2021 thanks to a fresh piston and clutch internals. The Sport minicycle range hasn’t been left out either: the KTM 85 SX gets larger discs and a completely new front and rear brake system. All three junior motocrossers now have a tapered handlebar allowing fitment of ODI lock-on grips. For the KTM 50 SX and KTM 50 SX MINI, the new tapered handlebar allows fitment of thinner grips.
Husky revamp
For 2021 Husqvarna says it has improved its suspension performance by adding a new mid-valve damping system to the WP XACT forks with AER technology. Additionally, new low-friction linkage seals offer a more refined response.
As with KTM, the Husky mini-crossers haven’t escaped attention. High-grip seat coverings are now used throughout the range and the TC85 gets new brake calipers and a smoother roller throttle action. The TC50 and 65 have tapered diameter aluminium handlebars.
