Exhaust parts for Honda CT90 / Trail 90 motorcycles

One of the defining features of the Honda CT90 / Trail 90 is its high-mounted exhaust, designed for off-road use and improved ground clearance. The exhaust system consists of a single pipe that exits the right side of the engine and runs up along the frame, protected by a heat shield to prevent burns. Later models featured a larger muffler with an integrated spark arrestor for better emissions control and noise reduction. Common leak areas include the exhaust flange at the cylinder head and the joint between the muffler and the exhaust pipe. Regular maintenance, including replacing exhaust gaskets and ensuring proper mounting, helps keep the system performing at its best.
