Installed the 50mm kit in a Leo Vince LV one EVO slip-on
On my 2025 Tenere fit perfect. Quality product. Arrived I a timely manner and came with everything needed to install even loktite.
I'm a registered professional mechanical engineer, and I would tell the engineers who worked for me that there is elegance in simplicity (some engineers tend to develop overly complex solutions).
Purchased the Fisch Moto USFS spark arrestor for my 2023 AJP PR7 and I was impressed with the build quality, ease of installation, and the overall simplicity of the design. It arrived in Arizona only 3 days after completing the order - wow! Comes with everything you need for installation; this is an excellent product!
I was apprehensive about the $120 price but it's quality build and inclusion of set screws (incl extras), t-handle allen wrench, and loctite makes it quite complete. Could've included a few extra stickers though. :)
Purchased this due to a local endureo requiring a spark arrestor. Product is as described. Good packaging. Timely delivery. VERY easy to install with all the necessaries being inside packaging. We'll see how it holds up during the enduro.
