Product Details
Big Gun is a well-known name in the powersports world, especially for their performance exhaust systems. Now, they offer an affordable alternative to stock CDI boxes with their Over Rev Box for the 2002-2005 Honda TRX 90. If you're looking to get a little more out of your engine, this rev box is designed to do just that.
This unit replaces your stock CDI box with a simple plug-in installation. It's built to increase the overall RPM limit beyond what the factory unit allows, giving you access to more power in the upper range. On top of raising the rev limiter, it also features an advanced timing curve. This means the spark plug fires at a slightly different point in the combustion cycle, which can help improve engine response and power delivery. It's a solid option if you're looking for an improved performance feel from your TRX 90 without breaking the bank.
Keep in mind that this part is not CARB approved and cannot be shipped to California. It comes with a 6-month limited warranty from Big Gun.
