For spike - fitting an alloy zx7r seat unit
Posted: Mon Aug 24, 2009 10:37 am
Here you go spike, a few pics of how I fitted a zx7r subframe to my bike. Its an easy swap to do and saves quite a lot of weight. Theres nothing complicated about it, just a bit of chopping and in it goes.
The bottom mounts at the front go straight on, then you can line it up at the correct angle and drill new holes for the top mounts. There is a rivetnut on either side that needs to be drilled out first of all. The petrol tank mount i turned over and put a bolt through it to mount the tank onto. The slots on each end had to be lengthened slightly as the subframe is pinched in a bit at the top mounts compared to on the zxr. You could weld a nut onto it instead to do this, i'd also think about making a new mount out of a piece of alloy bar as the zxr one is a heavy piece of steel.
You can chop the complete back section off for a race bike, i've left it there as mine is a road bike and its nice having plenty of space for luggage. The lower tube on the left side wasleft longer to mount the can hanger to. I've just fed the standard wiring loom through the subframe, but on a race bike you could shorten it and get everything bolted in and around the battery box area.
