Frankie's replacement - FXR/GP100 hybrid

[Slingshot]

After racing for about a year on Frankie I've decided that it's time to upgrade. There's only so much that can be done with skinny little tires.

I've managed to pick up a FXR frame, it was a bit of a score cause it came with a swing-arm and shock, front and rear brake calipers & master cylinders, left clip-on, triple clamps & bent forks.

After talking to a heap of people I've decided that I'm going to transplant the GP100 that's currently in Frankie. It looks like I'll be able to make up a bracket that will attach to the existing FXR engine mounts. So now all I need is forks, a tank and a set of wheels...speaking of wheels...

TSS hooked me up with a 17"x2.5" front off a CBR (for next to nothing) and fellow Norf Welly Massif member Sully60 hooked me up with a 17"x2.5" rear off a TZR. Mr Sully also helped me put the slicks that I'd got off trade-me and they look like they've got an ok profile!

Once I can source a sprocket carrier for the rear wheel it looks like the wheel will almost slot straight in, without modification to the rear caliper (almost looks too easy to be true). The front will be a bit more challenging but that will depend on what forks I go with. I'm planning to keep the FXR triple clamp setup so that I don't have to mess with steering head bearings, etc.


I'll update this thread with my progress.

Nice one, I have a FXR frame too, I've used RG150 triple clamps and stem, slots straight in but has the advantage of taking 35mm forks rather than the hard to find 33mm stock FXR forks. Seems a lot bigger choice in the 35mm range, I'm using RZ350 forks.

I've seen a sprocket carrier welded to a rear wheel. I think it was a bit hard to find the correct one to fit that wheel. Seemed to work OK. McIntosh race bike rear wheels did not have cush drives. The sprocket bolted to a sprocket carrier which bolted to the hub. Worked OK till you started getting up in the HP.

That's a good option, I'm also thinking I might get a couple of mm taken out of the existing triple clamps to make em fit 35mm forks.

Yeah, I'm not sure that the ponies that the GP puts out would be enough to cause the gearbox too many problems. Might have a go at making one if I can't find one....I mean....how hard can it be

[Number One]

I look forward to the naming ceremony

I haven't given much thought to a name for this wee beast yet.

Maybe another option for the forks is a GSX250R, late 80's model, have found that the stearing stem is a good fit length wise and they use the same head bearings.

Maybe we should have a piss up anyway...you know to help you think about it

I've seen this done to use a front wheel as a rear, if that makes sense!

Yeah, I know what you mean.

I'm using a 17" x 3.00" front wheel as a rear on Lady P with no cush drive.
A DT175 sprocket bolts up perfectly with the "front disc" threads.

It's "The Bride of Frankinstein".... or maybe it could be Francis... well tough shit, that's what I'm going to call it until someone thinks of something better. Look forward to seeing it out there kicking some arse at the Slipway Slinger!

The old man now has the bent forks and is going to have a crack at making em straight. It looks like the crease is at the point where the lower triple tree was clamped, so we'll see.

If that doesn't work, I'll start looking for 35mm forks and he'll bore out the clamps a little.
