First, the 450 four-strokes and 250/300 two-strokes come with the Belleville-washer-operated DDS (Damped Diaphragm System) clutch. There are two types of KTM/Husky/GasGas hydraulic clutches.

Six kidney-shaped rubber dampers (one of which is shown at the bottom of the photo) cushion the clutch from acceleration jolts.Ĭlutch models. This is the DDS (Damped Diaphragm System) clutch that comes in the KTM 450SXF and 250SX two-stroke (it also comes on selected Husky and GasGas models). (6) Riders who burn up the standard issue KX450, CRF450, YZ450F or RM-Z450 clutches in four motos will go months with a KTM Belleville-washer clutch. (5) The CNC-machined steel clutch basket has the primary gear machined into the billet of steel (instead of riveting a separate primary gear to the back of a cast aluminum clutch basket like the bies from Japan). On the typical Japanese clutch you have to remove the primary gear by drilling out the rivets to move it to a new basket.

Rather than delay the delivery of bikes to the dealers any longer than necessary, the KTM Group had to change the spec-and Braktec, which handles the brake and clutch fitment on several Husqvarna off-road models got the call to supply the later arriving GasGas models with their systems.ĭon’t know what clutch hydraulics your new GasGas has, look at the fine print on top of the clutch master cylinder-if it says Brakiec, then you don’t have Brembo…and you won’t have Brembo brakes either. Why? Remember the pandemic, supply line issues and work shutdowns? Well, Brembo couldn’t supply all the clutch parts needed to fulfill the production demands for KTM, Husqvarna and Gas Gas. However, if you got your bike from a later run GasGas bikes down the assembly, there is a good chance that your bike will have a BrakeTec master cylinder and slave unit. For 2023 KTM and Husqvarna motocross models use Brembo hydraulic systems and, if you got your 2023 GasGas from the first batch off the assembly line, it too will have a Brembo master cylinder and slave unit. (4) The KTM/Husky/GasGas clutch is activated by a hydraulic master cylinder and slave unit that self-adjusts as you use it.
