Product details
Built for serious racers, these RFX Pro Series Dual Button Launch Controls draw on more than 30 years of racing and engineering experience along with quality design, superior materials and advanced manufacturing. They let you pull the front suspension down and lock it, so the front wheel stays down when you accelerate hard out of the start gate. With two buttons to choose from, you can pick the one that suits the conditions on the day.
Button design
- Dual-button layout for rider preference in different conditions
- Extended plunger reach for full engagement
- Plunger positioned further out for extra clearance on newer KTM models
- Low-profile design that weighs just 20g more than a single-button version
- Hard anodised for a factory finish
- Four-bolt construction for added security
- Made from aerospace-grade billet aluminium and CNC-machined
Latch design
- Two-bolt fixing that avoids any interference with fork guards
- Deeper latch profile that stops it disengaging falsely at the start gate
- Hinged for simple fitting and a secure hold
- Machined on a CNC from aerospace-grade billet aluminium
- Durable, stylish hard anodised finish
- Laser-etched RFX Hardware logo
Leading UK race teams have tested these launch controls, so you can rely on their performance when the gate drops.
