K7 gsxr Swingarm set up in a slingshot 1100 k frame

[MooreMatthew]

Anyone put a k7 complete front and rear end in a slingshot 1100 k frame if so what was needed to do on the Swingarm side 

Also any pics 

Cheers

I put a k7 arm in a huc frame, they are designed to take slingshot running gear.

All i had to do was make some top hat spacers to sleeve the spindle size down and make up the width difference, k7 was narrower.

Also had to make some adjustable dog bones because mount is on the underside not the top.

I used standard slingy linkage and wheel.

Not sure on k7 wheels but earlier k series gsxrs ones are 110mm sprocket offset and slingshot are 100mm from centre of the wheel. Takes some sorting out, front sprocket spacing, hub/carrier machining if you want to do the job properly

Doesn’t sound too bad to fit 

just contemplating what to do now I have front and rear ends complete 

would you say the forks are too short for the slingshot and need a step yoke or extenders making

Not at all, i have run various k-series forks in slingshots quite a few times, my race bike handled really well, also gad about a 30mm lift at the back end. I had it on the road too. They seem to respond really well to steeper geometry and getting plenty of weight over the front end

Seems like a good combination.

That looks a proper build 

Originally was going to build it up fairly standard with some L forks but as always can't help bud to build something a little bit more special 

Might get some measurements and trial for the parts to my frame 

Did you have to swap stem out for the front end like you have to on most conversions 

Thanks

No need to swap stem, thats why you need funky size top bearing

[no class]

you can either look for the bearing locally or get the kit from " all balls racing " …..easy swap .

Get them from a company called Marksman for about £17.50

Thanks going to order a set and get the bushes for swingarm made then can go from there 

Thanks

Is the black powder coated.

Anyone ever anodized frame or swing arm. Would image cast bits would be not such a good black.

Aren't they anodized from the factory. there can't be much silicone in the alloy other wise the anodized would be "sooty". biggest problem will be finding an anodizer with a big enough tank.

[jonny1bump]

I thought the stock alluminium frames are lacquered hence why they don't look so good over time. Never polished frame hence question.

[dupersunc]

I'm sure they are anodized.

[jonny1bump]

Good point about finding vat big enough.

In your pic was frame and swing arm already black when you had it and is it paint or anodized.

Not my bike unfortunately.

Doh funny.

Have k5 front end in my 750m and k7 swing arm, As already replied front is easy just bearing swap,! Rear needs top hat reducers for spindle reduction! And linkage is a mare I tried many conatations and ended up fitting a 750m dogbone mount complete ! To top of my k7 arm and made long dog bones to suit, I also run remote resovior shock as no room for k7 shock (res) . 

Head scratcher for sure but got there in the end.

Meanbean47  how much did you machine of the sprocket carrier and did you have to trim the spacer ? I am in the middle of doing this as well hope you get this cheers

5mm off wheel/carrier and spacer to make carrier sit 5mm closer to wheel centre

That was about as much as its safe to take off K1 wheels

Yeah had to trim 5mm off the rubbers too. 

The other 5mm difference needed I did running a Talon sprocket back to front, and a 2mm spacer behind front sprocket
