This is a billet aluminum Y-piece used in the conversion of a modern Honda chassis to accept a 1989-2001 CR500 engine. This Y-piece is machined from solid blocks of 6061-T6 aluminum, then de-burred in a media tumbler. The front engine mount is machined into the Y-piece such that you will not have to fabricate front engine mounts. The ends are machined to fit either inside or around the tubing of the frame to allow the strongest possible welds. With this Y-piece, you do not have to replace the square tubes that run under the engine. We have many customers who have used this Y-piece for their conversions and we have received no complaints but many of them have commented on how much they like it. As you can see from the images it makes a very clean looking conversion. CR500 engines from 1985 to 1988 can be used but require the swing-arm bolt bushings in the rear of the case to be modified.
