Our Custom-Made Gear Gazers for the Ducati Bevel Drive 900 and 860 engines from the original Ducati bevel housing covers have been upgraded with even better components. The glass is even more durable than the majority of other gear gazers that are available in the marketplace. Will also work on the 750 engines as well. We also have the tooling set up to cut your own cover to fit the tempered glass for the Gear Gazer Cover. We have made a number of these for customers and for our projects with great success. If you want a unique and cost effective Gear Gazer for your bevel drive, then you will be pleased with these nice polished covers. We can also have them annodized or powder coated. I have a black crinkle finish powder coated gear gazer on my Big Bore 750 Desmo Spaggiari racebike. Many options.
