Track• Camoplast Ice Attak XT• Pre-studded• 1.22" lug profile• Traction and stability allows rider
to maintain speed - less fuel burned from excessive need to accelerate and decelerate• Added traction can contribute to
safety

Next steps• Reduce track noise• Means of reducing pumping losses (stay tuned!)
• EGR?• More exotic means...
• Refine fuel map and load calculation strategy• Consistency of load state calculation
• Weight reduction• New muffler design
• integrated catalyst
