BEC chain driven transfer / diff / reverse
has anyone fitted or has experience of one of these in a BEC
shown here on a hayabusa trike the diff / transfer box is chain driven with a 1/1 ratio i believe the final drive ratio is built into this unit as a
reverse gear
seems it might solve a lot of the issues with chain drive

Look to me like the rear of a Quaife / Poweretec box from the Radicals.
If so, then it is great... if you have three and a half grand going spare

Indeed... it's the perfect solution Aitch, but bloody expensive!

back to a modified sierra lsd and startor motor reverse
of course this has the advantahe of easily being able to change sprockets and therefore final drive ratios

IIRC some people have used a starter chain and sprocket on one side of the diff and a starter motor/sprocket on the other side for reverse. Might
make life a little tricky if planning inboard brakes but apart from that should work.
I know someone on here has done it, just can't think who...

Just out of interest, do trikes need IVA?

They go through Motorcycle SVA, which is a lot easier than IVA.
