Fits Honda Nighthawk 250/550 and 83-85 650sc as well as CB700SC.

If this is not the model you need, please send us a quick message and we'll be able to point you in the right direction. Yes folks, there are many, many, many sized used on various master cylinders. Do not assume that these will fit another model. Please check with us first.

Please note: These are press fit in place, you'll only need to remove your old trim ring and lightly tap this into place.  Be sure to cover the lens with a rag or cloth to prevent damage. They are OEM style reproductions. While these are a great option to replace your failing lens, they are not a long term solution like our traditional glass lenses. They WILL degrade over time. You can expect a few years out of these, possibly more. For a permanent repair, please order our GLASS replacement lenses.

Takes under an hour, very easy to do.

Due to a January 22nd 2012 price increase by USPS, international shipments for sight glass lens kits have been increased to $3.75, we apologize for any inconvenience.
