Diffuser connection rubbers for 2T motocross and enduro - tightness and flexibility of the exhaust
( number of products: 9 )
Diffuser connecting rubbers (exhaust couplers) are elements that are responsible for a tight and flexible connection between the diffuser, cylinder and muffler in two-stroke motorcycles. At Bajamoto you will findexhaust fittings of the highest quality - from renowned manufacturersM.C, OXA, FM-Parts and Tourmax - adapted toKTM, Husqvarna, GasGas, Beta, Sherco and Yamaha motorcycles.
Why is the rubber connecting the diffuser so important?
When the 2T engine is running, the exhaust system vibrates intensely and heats up. If the connection between the diffuser and the cylinder is not tight, the following may occur:
- exhaust gas blow-by and loss of power,
- uneven engine operation
- excessive noise,
- unsealing or loosening of the diffuser,
- increased fuel consumption.
Therefore, the rubber connecting the diffuser must be made of materials resistant to high temperatures, vibrations and oils - exactly those offered by M.C, OXA, FM-Parts and Tourmax.
Types of diffuser connecting rubbers
- Standard diffuser rubbers - flexible and tight, used in most 2T motorcycles,
- Reinforced rubber – thicker walls and greater thermal resistance, ideal for hard enduro,
- Rubbers with O-rings – provide additional tightness of the connection and dampen vibrations,
- Racing rubber – made of a mixture resistant to gasoline, oil and extreme temperatures.

How to choose diffuser rubber for a motorcycle?
Rubbers differ in internal diameter and length, so it is best to choose them according to the specific motorcycle model. At Bajamoto you will find dedicateddiffuser connectorsfor:
- KTM EXC/SX 125–300 2T – M.C and FM-Parts rubbers
- Husqvarna TE/TC 125–300 – OXA Racing connectors

- Beta RR 2T – OXA and M.C reinforced connectors
- Sherco SE-R and Yamaha YZ 125/250 – Tourmax universal connecting rubbers.
Installation and maintenance of the rubber connecting the diffuser
When replacing the rubber, it is worth using silicone or copper grease - it will facilitate installation and prevent the joints from drying out. It is also recommended to use exhaust springs (e.g. DRC, Prox, FMF) to protect the rubber against shifting while the engine is running.
Tightness, durability and peace of mind on the route
Don't let a small leak rob your engine of its power. Choose diffuser connecting rubber fromM.C, OXA, FM-Parts or Tourmax and enjoy trouble-free exhaust operation even in the toughest enduro conditions. At Bajamoto you will find only proven components that fit perfectly and last more than a season.
