Product Description
Your Beta RX is a powerhouse on the track, but the stock seat can be hard on your body during long rides. The Seat Concepts Comfort seat fixes this by widening the seating area and leveling the platform. This design keeps you from sliding toward the tank so you can stay in control. It makes your bike much more enjoyable for long days in the woods or on the track.
These seats use a special foam that provides great support and absorbs vibration better than the factory part. You can choose from Low or Standard heights, and even pick the Comfort XL width for a wider base. This is a complete seat that comes ready to bolt right onto your bike.

Beta RX, RXF and RS Comfort Seat FAQ (2025 to 2027)
What is the Seat Concepts Beta RX Comfort Seat?
The Comfort Seat is a complete seat that widens the seating area and levels the platform, so you stop sliding toward the tank. The foam is rated medium density, 5% softer than the factory foam.
Which Beta models and years does it fit?
It fits the Beta 300 RX in 2025, the 450 RX and RXF from 2025 to 2027, the 250 RX and RXF and the 350 RX and RXF from 2026 to 2027, and the 390, 430 and 500 RS in 2026. For the water-resistant version, see the Element Seat, and for the racing version, see the Race 2.0 Seat.
What is the Beta RX seat height, and what does this seat change?
The 2025 Beta 450 RX seat height is about 945 mm (37.2 inches). Standard keeps the factory height and is 7-5/8 inches (194 mm) wide. Low is 5/8 inch (15 mm) lower and 8 inches (203 mm) wide. Tall is 3/4 inch (19 mm) taller and 7-1/4 inches (184 mm) wide. Comfort XL keeps the factory height and is 9.25 inches (235 mm) wide.
Which covers can I choose?
The sides come in black carbon fiber, black wire, blue wire, red semi-grip or phoenix red wire, and the top in black sandpaper, black semi-grip, blue wire or phoenix red wire. Black carbon fiber is a semi-smooth vinyl-based material with low grip. Black sandpaper is the high-grip top: its texture is like low-grit sandpaper, it holds you in position, and it works best with purpose-built riding gear. Black semi-grip is the low-slip top: its beaded cross weave keeps you in position but lets you move around the seat, and it works with casual clothing such as jeans as well as riding gear. Wire gripper has a mechanical gripping texture that gives a high level of grip and limits movement on the seat in all conditions.
Is this a complete seat?
It is a complete seat, so you swap it for your old one. There is no kit option.
