Sukida SK125-2 Pharoah - Page 2

I have considered grafting a CG-125 front end on...... at great depth!

But it's a case of trying to find an intact one! Most of the bikes that are being junked over here all have smashed front ends!

There is a back street bike engineer semi locally who has a whole emporium of used/old/uncommon stuff from bikes he has stripped over the years. I spoke to him yesterday and he told me to bring the wheel & disc over and leave it with him for a couple of days. If he hasn't got anything, then we will engineer something!

Proper, old school engineering :-)

Well, I've heard back from www.learnerlegal.com - Having sent the link to the Chinese site, all the dimensons & a picture of the disc on the wheel.

Can't help, sorry!

More like can't be bothered!

Going to get in touch first thing Monday AM with the guys who have supposedly jigged it and straightened it. They have done something with it, as the disc and hub are clean.... but if they have straightened it it's either pinged back out of shape, or they have got the tea boy to do it!

Who would have thought that something as simple as a circular bit of metal would cause so much hassle?

In the interest of proper, old school engineering, can you fabricate a caliper bracket? If so, you could install a CG125 rotor and use your stock caliper or the CG125 caliper.

Another option is to have a CG125 rotor turned down on a lathe to match the diameter of your original rotor.

JRH · 02-17-2013, 12:02 PM

That's what I'm thinking....

Machining down a CG rotor is not an option, as they are 240mm outside diameter, versus 202mm of the Chinese. The friction area is roughly the same on both rotors, so if I machined down a CG unit, there would be no friction surface left - just the spokes!.

I've asked my friendly neighborhood bike instructer to drop the CG caliper back to me, so I can do some further investigation. There is only 5mm difference in the hole centres of the fork to caliper bracket. If I can get a CG bracket, there is a chance there will be enough meat there for me to slot one of the holes out a bit (just need to take into account how I'm going to fix it - the caliper bracket holes are threaded, if I can get a nut on the back all well and good), or, take the caliper bracket to a friend of mine, and have him fabricate another one up, but make it that little bit longer on the one edge to accomodate the wider hole centres. If anyone can do it, Harvey can - he repaired the frame of my other halfs GS-650 Katana a couple of weeks back, and you couldn't see where he had done it!

I'll drop the wheel and rotor off to "Ole Russ", and see what he can do first.... if not, then it looks like it will be the extra fabrication & CG setup.

There IS light at the end of the tunnel - but there are quite a few twists and turns before we get to it!

Thanks,

J

It'll be great if the gentleman from the bike wrecker / breaker can find a suitable replacement, especially if you know what it's from. That will make rotor replacement easier down the road. If not, then the fabricated caliper bracket and CG125 rotor sounds good.

JRH · 02-17-2013, 12:18 PM

This is the problem we have....

I have not been able to find out what the rotor is originally from! I've spend days trawling google images, looking at pics of just about every small bike from the mid 70's onward, and nothing even comes close (apart from the GL-145, but the local Honda agent laughed at me when I gave them the part number!). Nothing comes close!

The hub end is definately identical to a CG, as I have one here to measure against, but it's just the diameter!

I think it's nigh on impossible that the Chinese have actually designed something unique - they always tend to copy everybody else, save on design costs :-)

We'll get there..... the weather is getting better, and the missus wants to get out and get some road time in. Seeing as her GS-650 is still a bare frame, I'm under pressure with the 125!

xl185s pegs were mounted on the swingarm, too

I road one, but never looked at the rear pegs. I actually removed the passenger pegs from my lifan.

I would remove the pegs on the Sukida, but the UK vehicle test states that if there is a seat for a passenger, then the footrests have to be present - regardless of whether or not you are actually allowed to carry a passenger as per the terms of your license!

Have dropped the wheel and rotor off with Russ.... he says to give him a few days, and he will come up with a "cunning plan".

Sounds hopeful!
