suzuki xf 644 freewind unit

Postby flaky » Sun Feb 23, 2014 4:55 pm

can anyone tell me whether the Freewind engine/gbox unit has altered specification over the years that it was in production. I want to go down a tooth or two on my front sprocket---has the spline pattern or diameter of the shaft changed over the years the xf was in production? My ccm r30 was reg'd in 2003

I have had CCM 644 & DR 650SE & the sprockets have been the same fitment on those as I have swapped between them. I pretty sure the DR 650 hasn't changed from 1996 to this day so the Breakwind would be just the same.

What sort of riding are you doing on the R30 that you would need to change the ratio so much ? A 14T front is as far as I would go & I tried many different ratios when I had the trolley wheels on my 644.

there was a 16t fitted when i bought my r30.apparently 15t is fitted as standard for road use. 1st does feel a bit high.---when looking through the pictures of ccm adds on ebay most sprockets are multi splined,but some have only 6 splines. i think they may have changed around 2003.

They are still the same. Dont forget many pics on ebay are not of the model specific part but just a generic pic.

Look at this link which proves the fitment is suitable for all DR650 SE & XF650 models of any year which also means they will fit yours :tup:

This fitment is also suitable for all DR Bigs if you upgrade to a 525 chain.

yeah,thanks nug, that 6spline is definitely the one.i checked it out this morning just to be certain--- do you reckon a spring link in the chain would be ok?

You can use a breakable link but be careful as if the chin slipper is worn it will rub on the spring clip. Make sure you have the closed end traveling forwards as well or it can get pushed off the link. Thats not to say the same thing won't happen if you push the bike backwards. I personally prefer endless chains.
