Hayabusa Swing arm to a '99 Bandit 12

[Crazy88]

Hi Everyone

I have a question that I hope all you knowledgable people will be able to help me with.

I have a ' 99 1200 Bandit, and its turning in to a bit of a project.

I like the idea of a larger rear wheel and was thinking of putting either a Hayabusa rear wheel on or adding the whole unit, swing arm/ wheel etc.

I know the idea has probably been banded about quite a bit and was wondering if there is a thread that people know of that I could read or alternatively technical advice given on possibility/pro's/con's  ease of fitting or is it going to be a complete ball ache to do?

Will look forward to reading your comments.

Cheers

I have a JMC swinging arm in my b12 with TLR 1000 back wheel fitted. I just sleeved the spindle to fit the wheel and cut down a hayabusa caliper hanger. Mk1 busa, TLR 1000 and 750 Srad use the same back wheels

This one.

It's t bit bigger now, the dog that is

Not quite the same but I've got a gsxr1000 k1 swing arm with gsxr750srad 6" rear wheel in a gsx1100f and apart from having some sleeves made to reduce the swing arm bears to the gsx spindle, it went in with no fuss.

[Crazy88]

What size tyre do you have in the 6 inch rim?, I like the idea of a 200 section if at all possible.

[dupersunc]

What have you guys done about the chain line? The sprocket on the srad/tl/busa wheels are 10mm further out than bandit.

[clivegto]

Forgotten how I did the chain run now as it was a long time ago but I still have the bike and the dog.

Heres one I made 12 years ago, 6 inch rear end from a k 4 1000 I think,, the sprocket offset is the same though, 2 mm spacer under sprocket to end of spline, turned rear sprocket over and gained 2 mm, turned 5 mm off the carrier spacer and trimmed the rubbers so it moved  to starboard 5 mm, that made 9 mm to the right , chain cleared frame and just cleared the tyre, looked good but was definitely to fat as it turned slower than with 180 rear.

I have 4 bikes with 6” rears. One had a 200/50 from the factory, the others had 190/50.   All now run 190/55’s.  Only a fraction taller than a 200/50 which is taller than a 190/50 but it works well.   I’m a big fan of the S22’s in a 190/55 on 6” rims. The shape and profile means all mine tip in real well, except one that I needed to raise the rear a fraction to do it.

Bikes like the B-King used the Gen-2 Busa rear wheel, the Busa got a 190/50 and the King got a 200/50 on the same rim. It’s very common for owners of both to change to a more sporty 190/55.

I know a “200” should look like a proper big boys tyre but in reality it’s not that noticeable. I notice the improved handling more than the slightly smaller size look.

first mod I was advised to do to My TL when I started racing it was, fit a 600 SRAD 5.5 inch rear with a 180 55, to make it turn quick, and it did 

 

[Joseph]

Yeah nobody retains the 200 tyre on bikes that are fitted with them standard.

When i got my ZX12 that i dailyed for a year the rear tyre was shot. It went through several but i always used a 180.

Did look the business from behind with the stocker though 

[Tony Nitrous]

It depends on the bikes geometry and set up, but my de-fault go to pick Is normally a 180/55 on a 5.5”  and a 190/55 on a 6”.  

[wraith]

Like a lot of custom bikes, it comes down to how you want it to look over handling and speed 

I'm looking at putting a 6" in the gsx1157et just because, the bigger rear tyre will look much better with the size and style of the bike (I think).

You could always put a 65 or 60 profile on the front instead of the 70 to make it turn in quicker.

Also depending on tyre you use, say a Conti diamond that have a very pointy profile as standard.

[Dezza]

A 180/55 can be used on a 6 inch rim. A 5.5. is preferable but the problem is obtaining decent secondhand 5.5 inch wheels, especially fancy aftermarket ones.

[Crazy88]

So a general concensus is to go with  6inch rim but drop a size to a 190 for better turning?

As im a bit wet behind the ears with regards to all this, a Busa or TL rim 6 inch? And to clarify the best way to install?

Cheers and sorry if I sound totally dim

A 190/55 on 6" is a nice size in terms of riding but maybe you care more for the low profile tire look.

[Crazy88]

I like the idea of the low.profile and look but i also dont want it handling like pig when hooning about.

The donor bike

[Captain Chaos]

blue engine... WTF

[Crazy88]

I didnt paint it thank feck

[wraith]

You putting the front end on as well?

Them carbs are probably worth more than the rest of the bike that will be left once you have removed the rear and front ends 

[Crazy88]

Yeah Im going to be using the front end, hoping for the rear end hence this thread, see what i can sell the rest for if at all..rofl
