For the performance minded, Sumax offers their ThunderVolt line of plug wires. All spark plug wires fire intermittently, causing nasty carbon build up on your spark plugs. At 50 ohms/ft of resistance, ThunderVolt wires fire a positive stream that actually clean your plugs as you ride. You will see your bike start easier, run stronger and have the added benefit of more horsepower and foot pounds of torque. These wires are the top selling performance wires world wide. They are offered in two sizes, 8.2MM and 10.4MM for those that need more insulation on their wires. 8.2MM wires come in several colors: Black, Red, Blue, Orange, Purple and Yellow for $78.95. The 10.4MM sets are standard issue black ideal for the racing customer offered at $96.95 per set.

Classic Thunder Logo

Classic Thunder gives you the look of Old School Cool with modern technology. In the early 1900's, prior to the invention of silicone, the motorcycle industry used cloth to insulate spark plug wires. Sumax brought that look back with these 7mm black silicone wires. They come with the same silicone synthetic jacketing that resists heat, oil, and abrasion. The outer cloth jacket is rated at 450 degrees F.  A combination Kevlar Helically Spiral Wound Core with 350 ohm/ft of resistance delivers great spark energy, while improving power, idle, and fuel efficiency. Matching Black Silicone Boots protect against high exhaust temperatures.  Custom Fit Colors offered: Orange with a Black Tracer, Yellow with Black & Red Tracers, Black with a Blue Tracer, Red with a Black Tracer, and Gray with Brown Tracer.

Extreme Duty Battery Cables

Extreme Duty Battery Cables deliver the "Punch of Power"!
They are really that good!

extreme duty

Battery cables by Sumax are the ultimate high performance battery cable on the market today.  Uniquely designed, these black 2 gauge, 180 amp rated cables will transfer more cranking power (with less voltage drop) than any other cable offered by their competitors. These very fat and very flexible cables have over 2000 bare strands of copper wire, are covered with special vinyl insulation and cased in a synthetic thermo rubber jacket. Terminals are closed-barrel style made of tinned copper (1/4” & 5/16” eyelets). Sealed insulated black heat shrink-tubing means no moisture will get in these cables. For bikes with starting problems or for a high powered one-two punch add a set of Thundervolt wires to the mix. These battery cables are offered at $92.95 per set.
