Two Brothers M series exhaust canisters feature the highest level of quality construction and are designed to be fully serviceable in the event of damage (replacement parts are available). The exhaust note produced by all Two Brothers Top Level exhaust systems is best described as being deep and throaty without suffering from the shrill whine normally associated with other manufacturer's straight through muffler canisters. All of the canisters perform and sound the same, they are simply different shapes. They all incorporate Two Brothers exclusive technologies and premium construction materials. The shape and orientation is normally determined by Two Brothers R&D department, based on a performance criteria check list. All aluminum systems include U.S. Forest Service approved spark arrestor.

Its a matter of survival. In an unforgiving maze of gravel strewn corners and malevolent steel a rider needs protection, vision and comfort. The call to arms has been answered. Introducing the Icon Variant helmet. The wind tunnel refined shell, executed in a Fiberglass / Dyneema / Carbon matrix, forms a solid first line of defense. Internally, a dual-density EPS core provides critical Energy Management, greatly reducing impact forces transmitted to the head. Of course safety is best affected by avoiding the crash altogether. To this end the Variant features a reshaped eyeport which provides enhanced peripheral vision. The Variants unique visor system also contributes to improved vision. When properly designed, such as on the Variant, the visor can help block bright sunlight while producing minimal lift characteristics. Couple this with Icons Fog-Free coating and it is obvious why the vision aspects of the Variant are superior. Another important method of increasing safety is by reducing rider fatigue. Excessive heat buildup can result in both discomfort and distraction. Neither a good situation. The Variants extensive venting system works at all speeds providing necessary airflow to the helmet interior. The airflow works in conjunction with the wicking Hydrady liner to effectively reduce heat buildup.
