Posted: Mon Feb 27, 2017 10:56 am Post subject: small sprocket for a DB1 |
|
|
the small (15 tooth) sprocket for my DB1 is sadly cactus. As usual when the problem should be straightforward it isn't
Let me elaborate
The sprocket is cup shaped inside, with a similar cupped washer that fits inside, it is then secured with an aluminium plate with a hole in the middle, this allows the whole assembly to be secured to the output shaft with an M8 bolt.
Trouble is after asking my local shops etc none of them seem to have the same sprocket, and the trouble is all the alternate ones seem to fit on the wrong section of the shaft to allow correct chain and wheel alignment.
Any advice guys? |

You need a "bimota Specific" DB1 front sprocket....DB2's and some others bikes are the same...specific sprockets on the front to ensure correct chain alignment...Its almost as if Bimota design and make the entire bike...ensuring wheel alignment...throw in cush drive assembly and standard=ish rear sprocket....chuck the engine in...and then realise a standard Ducati front sprocket doesn't achieve the correct chain alignment...thus they design the front sprocket last........Have you tried BCP in Italy for spares?....I have a couple of spares but they are in a secure remote location with other paraphernalia.... |

yes, I looked on eBay Italy after posting. He has the correct type. 126 pounds (UK money). Expensive but what else is there? Post from Paolo is always on the expensive side also, I get him to throw a couple of bits in to make it worthwhile |

Check with Steve at Bevel Heaven; they have a good selection of all spline types and offsets, he is quick to respond and very helpful/knowledgeable:

Alternatively you can fit a 750 PASO output/layshaft as this has a larger offset to compensate for the 160/60/16 rear tyre and gives a straight chain run with a flat sprocket with no offset.
Maybe conside a 520 chain conversion at the same time.... |
