The performance-focused minds at Riva Racing have unveiled eight new products for Kawasaki’s Ultra 300X/LX models that promise to boost power and improve handling.

Riva Kawasaki Speed Control Override Module ($249.95)

The Riva Speed Control Override Module removes the restrictive speed control function on Kawasaki Ultra 300X/LX models and promises to deliver significant increases in top speed with stock ECU.

Riva Ultra 300 Performance Power Filter Kit ($249.95)

According to Riva Racing, this kit delivers greatly improved acceleration and increased top speed by replacing the restrictive stock intake system. The Power Filter feeds your supercharger with an increased volume of air via a large 4” diameter intake duct and oversized K&N filter element. Ducting is precision formed from a race proven composite that will not conduct heat to incoming air. The kit includes a water-repellent pre-filter and is IJSBA?legal for all classes.

Riva Ultra 300/260/250 Bypass Upgrade Kit ($99.95)

According to Riva Racing, the Bypass Upgrade Kit is easy to install and contains all parts necessary to redirect hot air from the engine’s bypass valves and crankcase vent. This eliminates power-robbing engine emissions from entering your air intake system. The kit includes fitted K&N filters for bypass & blow-off valves and?crankcase vent (`07 250 models). This kit is designed to work with both Riva?Pro-Series &?Performance Power Filter Kits for Ultra 300 & Ultra 260/250. Click here for more information.

Riva Ultra 300/260/250 Free Flow Exhaust Kit ($249.95)

This exhaust kit enables you to bypass or remove the secondary muffler (weight savings of +10lbs), improving engine performance by reducing back pressure and harmful detonation.

Riva Ultra 300 Tunable Top-Loader Intake Grate ($249.95)

Riva’s fully tunable Top-Loader Intake Grate for the Ultra 300 features an adjustable foil & removable rear inlet chip. Developed through a joint effort with TBM Racing, this grate provides riders with the ability to tune for specific riding style or water conditions. The center foil has three positions or can be removed entirely. In flat water conditions it can be raised to the highest position increasing speed .5mph. Or be removed completely producing the same speed as the stock grate. The deeper center bars and removable rear inlet chip dramatically improve handling and hook up. The rear inlet chip can be removed or used with or without the center foil. Whether you’re a closed course racer, offshore racer, or just a weekend warrior, Riva says its Tunable Top-Loader Intake Grate will enhance the hook up and handling of your Ultra 300.

Riva Ultra 300 Performance Ride Plate ($289.95)
