The plan is a RS125 front end with clips, single under slung headlight, cafe single seat, standard pipes but cut off at just under foot pegs.

Well thats the plan anyways! lol

Hello mate, I can see you're having fun with this oldie. I'm sure you already know this but just in case it helps, it looks like your bike is a CB-250 G5. You will be able to find loads of Honda's of that period with the same carbs as yours. Gaz thumbsthumbs

Yep the plan is for pods but thats a way off yet.

Post man brought me the rear brake set up and it was as described



What I didn't think about is that because the drive side of the Aprilia is not the same as the Honda, and I'm running the rear wheel backwards the caliper mounts point the wrong freakin way!!!!!!!!

Damn it.

Any ideas of 125 sports style bikes with the brakes on the near side?

Pays me to look at a job properly before commenting on how things don't fit!

I was offering the caliper up under the swingarm as thats how I wanted to fit it.

But now I've had time to look at it in the original 'above' the swing arm position I am liking it. I've taken a little time to make a carrier template out of card and will also make a template of the bracket I'll have to weld onto the arm itself.

Picture will follow but im a litle board waiting to pick the kids up from school.

Stay tuned!

First attempt at caliper carrier.



Any thoughts ideas for improvement welcome.

The plan is to have a piece welded onto the swingarm then run 2x mounting bolts through the brackets with a spring between the parts to allow for a little movement.

hmm, could you use that plate you have made but instead of welding it to the swingarm make it so the rear spindle goes through it then run a torque bar to the swingarm?

Hey Mark

Did think about this as my 'Plan A' with the under slung caliper.

Problem is mounting it at the top there's nowhere to run a torque bar as the damn suspension gets in the way. Personally it is the preferred plan but ain't gonna work unfortunately. So it's plan A.1 (at the moment)

hmm yeah i see what you mean, you could always make one that goes around the shock would still be nice and strong if you made it beefy enough , gotta remember only 25% of your braking comes from the rear.

or make a bar that goes from the top of your plate to the back of the shock mount, dont know how much room you have back there or if it would be strong enough?

Problem with any torque bar is the fact that the rear wheel is as fat as it is.

Think I'm gonna solid mount it all.
All I've done is made another template and mount it to the outer side of the caliper.

Got my hands on some plate. Not overly interesting but it's still progress.





Only had 20mins after work to play with tools as the better half is off out!

But hopefully get some more time tomorrow night.

Mark - we've got a plasma cutter at work but the workshop is about 10 mile from the office so I don't get over there much.

Madsod - sorry couldn't resist.

I know what you mean but theres not gonna be that much movement (I hope) so going for a solid mount (maybe extend the holes caliper end to allow for a little adjustment)

Ok so we're changing direction with the caliper mount...again

Found this on eBay for less than a fiver thumbs


And it looks like this


I can then with this setup use a torque bar (I know I said there's not enough space..... I'm wrong again)
I could either shorten the original one or bend it a bit to clear the tyre.

Dude remember to watch what tyres you have fitted. With that, I presume is a 160 rear tyre?? It will stick to the road like dried shit to a blanket.

The issue is the frames back then are no way as stiff as they are today, hence the skinny tyres. You raz into a corner the bike will stick to the road but the frame may well melt. Very Happy

It's a 150 rear but will be replaced with a 140.

I was made very aware it the difference in the old tubular steel frames verses ally ones when I rode my old 350lc back to back with my mates nc31.

Bit this thing isn't being built as a race bike.
It's all about the looks baby!
