Is your Kawasaki ZX-14 running too hot or too cold? This thermostat and O-ring kit from Caltric might be the fix. It's a brand new, direct replacement for OEM part numbers 49054-1067, 49054-0004, and others. The kit includes one thermostat and one matching O-ring—everything you need for a proper seal. The thermostat itself is 40mm long, made from metal, and uses a simple bolt-on mounting style. It's designed specifically for the 2006-2011 Kawasaki ZX1400 Ninja ZX-14, so you know it'll fit right. Caltric backs it with a 90-day warranty, which is pretty decent for a motorcycle part. Installation is a bit technical, so if you're not comfortable working on engines, you might want a mechanic's help. Keep your bike's cooling system in check and avoid overheating issues. A small investment to keep your Ninja running cool and smooth on every ride. Don't wait until you're stuck on the side of the road!
