COOL FACTS
• The electronic gyro stabilization system is the most notable upgrade from the original VMX motorcycle which the MM 450 is based on. This is the device that makes it possible for the MM 450 to tackle off-road terrain and stay upright. Housed inside of the rear wheel is an innovative design where a brushless motor spins a weighted flywheel at over 12,000rpm to create a gyroscopic effect for stability. The VMX used a geared gyro system where its speed varied because it was directly linked to throttle input. On the other hand, the E-gyro on the Deegan dirt bike maintains its speed throughout the entire run to give it optimum stability.

• Atomik engineered the patent-pending mechanical traction control system (MTCS) into the MM 450 to allow for adjusting the bike for different types of terrain. Different blocks are included to change the location of where the swing arm attaches to the frame of the cycle. It comes out of the box with the MTCS at a neutral setting or it can be switched to handle low or high traction surfaces.

• The tunability does not stop there. A droop screw controls rear suspension travel for loose or high traction. The oil in the shocks and steering link can be switched to different viscosities. The position of the rear shock can also be moved to one of six mounting positions on the frame of the bike to fine tune to the surface where you will be doing the majority of your driving.

• Atomik gave this bike plenty of horsepower with the potent V550 4200Kv brushless motor controlled by a waterproof 80amp ESC complete with cooling fan. Other high-end electronics include the 2.4GHz 3-channel computer radio system, a 30amp waterproof speed controller for the E-gyro, a high-torque steering servo, a Venom 2S 3200 LiPo battery pack and 2-3 cell LiPo balance charger.

• Styling on the MM 450 is second to none. All the details are here, from the super realistic knobby off-road tires to the engine, exhaust and radiator details. Placed on top is the mini Deegan driver figure. It is molded of Neocell foam that proves to be very resilient and provides the ability to add loads of detail like the rolls in the leathers.

• A real steel roller chain drives the machined aluminum sprocket and propels the bike. The power comes from an adjustable slipper equipped spur gear that is spun by a pinion mounted on the brushless motor.

MAINTENANCE & TUNING TIPS
• The rider’s feet can be screwed onto the foot pegs, but leaving them loose will keep them from becoming hung-up on obstacles thus causing the bike to crash.

• Once you become accustomed to driving the MM 450, remove the metal nerf bars from both sides of the cycle and this will allow the bike to lean more in the turns and give you more control.

• If your Deegan dirt bike wheelies too much, try loosening the slipper clutch. Make slight adjustments a little at a time while driving the bike after each change. The slipper will become damaged if it is too loose.
