New guy to Buckets

[mossy1200]

Took the front end apart today. the tripple was a mess but the bearings were good. Looks like bearings replaced onto old shaft which is worn at the top bearing area. Im thinking the aprilia front end will need a new shaft custom made to work. Its in Wellington but not delivered to me yet so I guess ill find out how much work ill need do tomorrow to make this work.

Got a new muffler assy today. The ones on the bike weigh about 4-5kg and the new is well under 1kg. i think I saw one of these on another bucket last weekend.

I would assume your dimensions are 30x55x17 lower and 26x47x15? that what most of the era 250's are these dimension are shared by quite a few Honda's and Suzuki's.It may not be a matter of a custom shaft rather just fitting the honda shaft to the Aprilia yokes.
You never know it could just involve a bearing swap and a spacer to take up length if you are lucky.

Its possible I could just be looking at a new top bearing but I could always turn a new shaft to the honda spec and weld that into the lower clamp and use a sleave to make up the difference in the top. Its possible just a new top bearing. Will know more when I have the new front end. its at the PB transport depo in lower hut at the moment so it should arrive tomorrow. The lower honda bearing is the larger shaft size of the two. The honda shaft shaft is smaller at the top. Im thinking the aprilia shaft is same top and bottom. Also the top off the frame seems to have 2 sizes of outer bearing holder steps and it currently uses the lower smaller of the 2 so maybe the larger will be usable with another honda bottom bearing installed at the top.

This is the size of the 250 rs Aprilia bearing the origional are said to be $250+
25x47x15 upper
25x52x16.25 lower

but wait it looks like the bearing for your forks may well be.

Inside Diameter: 35mm
Outside Diameter: 55mm
Width: 14.5mm

huge so you might need to sleeve the std Honda stem into the Aprilia yokes

is a rsv1000 front

yeah found that it looks like the bottom numbers are it thats a big stem But then again its from a big bike.

It may be that I weld in a 16mm shaft for the top half and use one of these(pic bearing) and a bottom bearing from the rsv or remove the entire shaft from the rsv and make a shaft to the honda spec and use the original bearings.

mmm...maybe those forks are not so cheap in the long run.... Oh well nearly unbeatable with regards to the bucket bling factor though.
it would be interesting to see the total cost of the project as i guess the spend will exceed mine anyway, at least.
Having said that, er... yours actually runs.

ps measure up the mounts for the calipers when you get them.

Wife not complaining yet so build is still affordable.

Both front and rear suspension arrived today.

Fitted the rear 2010 r6 shock which bolted straight in with zero mods. Result was rear lifted 20mm approx. Static sag 10mm with zero adjustments. Plenty of bling to fiddle with so should work well. Original eye to eye was 285mm and r6 is 290mm. Even the spring weight feels good but need a ride to tell more.

Front end did some work. Need a small amount of internal lathe work to mod my bearings then a 16mm shaft to put it all together so will drop the parts off to engineer tomorrow that.

Question

The only bearings I can find that will fit the aprilia axel and cbr wheel are 6905 25/42/9 . Do you think 9mm is wide enough for a bucket? I think its possible to fit two 9mm at one side and 1 at the other. Would this be worthwhile or does anyone know of a 25 internal 42 external thats wider?

I dont really feel like going to a thinner axel eg 20mm as it would need be a mission to get that into the fork design unless I went axel inside original using the original as the axel bearing spacers and had nut and bolt axel within.

Why run with the Aprilia axle its made for a far far heavier bike. plus you already have a wheel that suits the std front axle is the std Honda one not wide enough as it would think it would be easier and cheaper and probably safer to sleeve the aprilia forks to suit the Honda axel or one the std Honda size? I GUESS I AM MISSING SOMETHING HERE?

One side of the aprilia forks is thread screw and the other is very large as it has a quick release front end system.
cbr axel is a 2 piece unit at 15mm and not wide enough so would need to make a new axel. Because of the large differnce from 15mm to 25mm thread and about 35mm on the other side I would need to turn a 35mm shiney steel shaft to 20 mm along most of its length and then make a new thread end with internal thread spacer at the other to take the made axel.
