Chain and sprockets time
Hey guys,
Going to change my chain and sprockets time. Couple questions tho. I’m looking to go back to the standard 15T Front and go up at the back, has anyone went up at the back? Was thinking 42T Rear would be reasonable! Has anyone went bigger? 44T Rear? Also was think of a 520 conversation too. Any thoughts and advice welcome. Thanks again. |

Hi, Ron
I'll be trying 15/42 when I eventually replace the chain and sprockets. Don't forget you'll need a longer chain i.e. +2 links to 106 links. While I believe that a 43 tooth rear will still work with the 106 chain, I think clearance with the upper chain guard would be marginal, so a 44 would probably be too large. |

Anybody had experience spec’ing Renthal chains.
So far I’ve managed to source the following: 15T Front Sprocket is renthal part no.433-525-15 42T Rear Sprocket is renthal part no.358A-525-42HA All well up to that point. However everywhere is pointing me the standard 39T chain fitment. Best I can see is the correct chain is renthal part No.525R4SRS-120 |

Does it have to be Renthal, Ron? I've currently got a DID X-ring and it's wearing very well so I'll be replacing it with the same again (but with 106 links).

It's just a slightly more mechanically sympathetic way of achieving (virtually) the same gearing.
In theory, the smaller front sprocket gives the chain a harder time as it has to make a tighter turn to negotiate the sprocket. Also, the smaller front sprocket reduces clearance on the upper chain run so the chain can rub on the nylon swingarm guard and wear it away over time. The advantage of choosing the small front sprocket is that it's quick and cheap. On the other hand, retaining the standard 15 tooth sprocket and fitting a larger rear will give the chain an easier life and avoid any rubbing on the top run. The downside is that it requires a longer chain (106 links). My 14/39 set up is working fine for me at the moment and I won't be changing just for the sake of it but, if and when the chain and/or sprockets wear out, I will replace them with a 15/42 arrangement. |

What sort of life are you getting out of a chain and sprocket set?

You can’t go wrong with Tsubaki Chains & Renthal sprockets from B & C Express.

By the time mines get replaced (full renthal set currently) they’ll be on about 18k. Atm they’re on 16k and the rear teeth are getting a wee bit pointy and sharp front isn’t to bad with only the slightest hint of hooking.
I’m a bit of a Lehman when it comes to chain wear but no matter the sprockets need done so chain will get done too |

A 14T sprocket will wear out 7% earlier

Recently replaced transmission to 15/38 (standard) and found she handled better in traffic - 'all be it' top speed is still ILLEGAL !!!
