Fits perfectly “ will be easy to remove and service to. Fischmoto great service from are Canadian neighbors . Showed up in a few days and was out riding in my local trails “ up to USFS standards .
Zero disappointments through entire purchase. Arrived quick, packaged extremely well, solid well built product and a fit like it was made for my bike that is 46 years old. Searched the entire internet and convinced this is the best product. And when you get it and see the quality of packaging and quality of product and fitment you know you got your moneys worth.
I needed a sparky for my SSR 140BW pit bike so I don't get hassled putting around camp and basic trails. This SA fit the bill perfectly. While the muffler on the bike has an unusual end cap shape, this still fit just fine and looks right at home.
Purchased a kit 50 for my GPR Trioval exhaust pipe on my 2025 DR650 and it fit perfectly. As a disclaimer, I don’t have the baffle installed. The opening without baffle was 2.4” but it fit perfectly with very little play in the sides. Great add on to become USFS again.
I bought a bike that had an expensive aftermarket silencer on it and needed a Spark Arrestor for Crown Land Riding. I found the Fisch Moto USFS approved Spark Arrestors and thought I would give it a try. A quick measurement of my pipe and the order was in. A few days later it arrived. Installation was dead simple (they even supplied Loctite for the set screws!). It is a very securely mounted system. Performance is unchanged. Thanks Fisch Moto for a quality solution!
