17 Tooth 530 Front Sprocket

[GregT]

Some years back I had a customer who changed his GSX1100 to a 17T front. After I'd dialled the cams and set it up properly his wife complained she was close to being lost off the pillion under acceleration - so he put the 17 on to soften the hit.
I made up an 18T 520 front for the race GS1000. OE Suzuki splined center machined to take a ring of teeth from another brand front - and TIG welded. At that time I couldn't find an 18 in the Suzuki/Kawasaki spline.

Just for info I have been running 17/46 530 on my GS1000 for over a year with no clearance issues or noticeable extra wear on the chain or sprockets, I have a GSX aluminium swinging arm as well.

Apart from choice range,I would never remove the bigger chain for a smaller.
All three of my bikes all 1100 plus run 63.
Always for the last fourty years used sybaki chains, early years on all my triples and Z9 not even O ring,never had a problem

Good for you, but you'd be surprised at the tensile strength and life-span of modern chain compared to 630. The Kawasaki 1000 H2R delivers 200bhp and 137.3Nm of torque through a 525 x-ring

Here's the size comparison. 630 to 520.

The Honda 750's used 530 thru "76" then changed to 630 because of the 530 breaking, Remember the old after mkt. dual row chains & sprockets made for the CB750's? In "77" the 630 fixed the chain problem. Today the 530's are stronger than the old 630's of the "70's & 80's, so going from an old 630 to a new 530 gives extra strength plus lot less rotating wgt. Hard to imagine not changing.

In the last 10 years the research money has gone into 520 chain. Everyone wants lighter, narrower chain which lasts. A good modern 520 will outperform your old 630.

But nothing has the visual impact of a 630. :cool-new:

 

[GregT]

If that was a factor, we'd all be using chromed triplex.

Seems I'm not the only one jealous cause I don't have a 520.
