|

Rode the Dieci to Dave Moss suspension clinic at Pro Italia. Besides realizing that my clutch is going i was advised that my SW rear shocks has air in it needs an overhaul. Do I have an option to go with an Ohlin rear shock? Other options other than Ohlins? _________________ 1991 Bimota YB10

I had one built by Maxton in the UK many years ago - don't know if they still have the spec. YB8e has an Ohlins on.
Clutch is most likely to be slave or master, rather than the clutch itself. There's no adjustment. _________________ What, Jonny's gone! |

Hi
Looking for a replacement for my YB10 rear shock - Wilbers list a YB8 fitment (but not a 10). Are they exactly the same fitment?
Thanks

It doesn't really matter that much. When I needed a new shock for the bb1, Wilbers built me one. I think it's the only bb1 shock they have made so far.
My point is that Wilbers will build what you need, but they will of course need some info regarding the old shock, bike, wheights and dimensions.
Other here will surely tell you if YB8 and YB10 share the same shock. _________________ Anders

Dieci has the same frame and same swing arm as an 8. So very likely same shock. Original on the 8 was a Marzocchi. _________________ What, Jonny's gone! |

Hi,I realise that you may have already gone down the Wilbers route but just FYI the Ohlins reference for the shock that fits the YB4/6/8 is Bi 815.Although the Dieci ws originally specified as offering an extra 10mm of suspension travel compared to the YB8 i am sure that any shock designed for the YB4/6/8 would be fine on your YB10. This Ohlins shock uses the STX46 body and has remote height adjustment .I recall that list price is c.eur1600+,so really not a cheap option,but you may be able to search out a decent deal on the net .I have done a quick search and found sellers at USD900 (+ import duty etc? )and an easier deal at www.crazydeal-moto.com at EUR 1097.66.Still not cheap but this does include the luxury of remote height adjustment.
One other option ,if you've got the energy,is to contact Nitron for a bespoke build.A couple of friends did this a few years ago for 2 Bimotas and you can now see that Nitron list shocks for the Mantra and YB11.These were bespoke builds requiring a visit to the factory where the bikes were stripped down to enable measurement and assessment of all critical parameters including the ratio of shock movement to wheel movement. Obviously this involves a fair amount of commitment but woukd help all future owners iof YB4,6,8 and 10 models.in addition Nitron offer a number of shock options ranging upwards from c.£450 depending on complexity but all their shocks are high quality .
Hope this helps . |

Hi,hope the extra details help you make the decision.Just for extra clarity :the Ohlins shock (Bi815) has separate rebound and remote compression adjustment as well as ride height adjustment (in addition to your adjustable dog bones ) and remote adjustable preload so is pretty much at the top end of spec options .
If you want a simpler option then the lower spec versions of the Nitron could be a good option.Alternatively the M-shock from Mike Capon at the Shock-factory could be a good option.Again this would be a bespoke build of very good quality at a very reasonable price .Nitron are in Witney ,near Oxford and the Shock Factory are in Market Harborough ,near Corby .
GOOD LUCK!! |

I explored as many option as I could. A company called Race Tech https://racetech.com/?fbclid=IwAR1op_LMtjt71RdNJA09SH0h23k8o5pSLGG8KEmmuC9jM2iC_m1_CjOly6M
offered to look into rebuilding the current SW shock for a very reasonable $280 with a caveat that they were not certain to have all necessary parts. They also offered to make one of their custom shocks for $1100.
I am not planning to sell the YB10 any time soon, if ever and the difference between a custom built Race Tech shock and an Ohlins shock is roughly $350 but also includes installation. I am familiar with Ohlins, plus it will add much more overall value to the YB10. Hence I placed an order for the Ohlins yesterday and should be receiving it within 30/40 days.
Great riding days are upon us here in So Cal and I can't bear seeing the Dieci just gathering dust in the garage. _________________ 1991 Bimota YB10

Wilbers are a much better shock than the older style Ohlins. Hi and low speed compression damping to start with. Beautiful german engineering, and made to suit your weight and riding style. plus you can order them with remote preload adjuster at extra cost.
Terry Hayes here at Shock Treatment in Australia (he invented the racetech gold valve) said to me over the phone that " Wilbers are a very very good shock" He isn't prone to exaggeration! |

Tirefriar, I have used Dave at Fast Bike Industries for my suspension work. He worked at Ohlins USA for years and went out on his own. He has access to hard to find parts and made me some custom built forks and shocks. Prices are reasonable and never had any problems. Since he is still friends with Ohlins, he was able to find the build sheets for my DB2 Ohlins Shock and convert it to a DB4 spec shock by matching the shim stacks. The only thing that wasn’t available was the Bimota shock spring (he said it was a one off progressive spring that Bimota had made). He can also adjust the length of shocks. https://www.fastbikeindustries.com/ _________________ 2002 Cannondale E440
