kz100p trike conversion questions

Hey. Long time since I was on, but I got a project I have to get done. My dad was trying to get back on two after 25+ years and failed his class. between his feet and knees he is finally admitting being two up is out. So I'm planning on building him up a KZ police trike but I got some mental road blocks.

I need to get it down some so it doesn't keel over on a turn when triked. How much am I going to be able to lower it? I can can do an up-swept the swing arm to lower the rear and put on shorter shocks to keep angles right and the tires will soften it up some to help it glide a bit nicer for his aging bones, and dropping the rear is less issue with no tire in the fender. But with the front how low am I going to be able to take it without scraping every time he leaves a lot or comes across a speed bump. I can work the exhaust a bit running oval or rectangle pipe underneath. and the bags can be lifted.

Does anyone know the distance from the drive sprocket to the bike center line?
gotta get a spec before I go buying an axle. I'd like to use an old Harley unit as they can always be found, but I need to know it'll fit.


Pop is beating the hell out of himself. Gotta show him the world hasn't ended for getting back in the wind.

prolly need to keep at least five inches under it depending on the roads you plan to travel.

i have seen several trikes built by using the swingarms out of quads.

a buddy of mine has a r6 with the swingarm and rear axle brake assembly out of a yfz450 under the back.with some front wheel dirve honda wheels adapted on.

can't help on the centerline number.
