As part of the Yamaha’s 600 series, your YZF600R exhibits the manufacturer’s ability to diversify and engineer a core design for different riding styles. Naturally, you want the best parts, accessories, tires and motorcycle apparel on the market. Whether you’re restoring an older model to race-worthy condition or you’re equipping a model you already use on the road, you naturally want to tweak key aspects of its performance. Several aftermarket mods can help you achieve these goals, but there are three absolute must-haves you should consider to make substantial improvements to your 600R.

OEM Versus Aftermarket

You’ve likely seen people talk about the merits of OEM and aftermarket parts, or encountered a guide to help you choose between the two. If you haven’t yet, then welcome to the world of motorcycles. Both types of components have their merits and provide specific advantages.

Think of OEM genuine Yamaha YZF600R parts as basic building blocks for your bike: the components that ensure that its engine performs dependably to factory specs, its fairings cut down on air drag and its body withstands the rigors of your ride. They’re also ideal if you’re attempting to preserve a bike’s retail value. On the other hand, aftermarket mods offer performance and style changes that differ from factory standards. Most riders want to improve engine power, speed, weight, aerodynamics, braking precision, or comfort.

Tires: Metzeler Sportec M3

Riders who swap out their tires usually want better handling and durability: two vital qualities that the Metzeler Sportec M3 delivers. The Sportec M3 features a uniquely designed compound that’s engineered specifically for the huge power output of high-performance sportbikes, providing high grip and great mileage. Not only that, the M3 includes a profile that’s balanced between the front and rear wheels for better handling and stability. These qualities make it a top choice among Thundercat riders.

Gearing Ratio: JT Sprockets

Sure, you’re going to find tons of guide that talk about changing the gearing ratio on your bike. Yet it’s a point that bears repeating because of the potential benefits. Most want to improve acceleration or how their bikes perform at lower speeds. JT Sprockets’ steel sprocket is a solid performer regardless of your specific goals, balancing strength with lightweight construction. Each sprocket is heat-treated and sandblasted to cut down on material surface tension and ensure consistent durability and performance.

Battery: Shorai LiFePO4 LFX14A1

Changing the stock battery on your Thundercat is also ridiculously easy, especially if your goals include weight reduction or faster cranking. Riders give high ratings to the Shorai LiFePO4 LFX14A1 battery for several reasons. Weighing in at 1.88 pounds, this lithium-ion battery significantly lighter than the stock Yuasa YTX12-BS. It also supplies more cold cranking amps: 210 versus the stock battery’s 180. This eco-friendly model is a drop-in replacement for the YTX12-BS and can hold its charge for up to one year. With so many benefits in one battery, it’s no wonder that the Shorai LFX14A1 is a popular alternative.

Hopefully, these ideas give you inspiration for modding your Thundercat. Choose a trustworthy parts supplier when shopping for your gear, and don’t forget to stay safe and suit up with high-quality motorcycle helmets and riding gear.
