Tesi 3D front suspension setting

[Bimota fan]

I have a question regarding the pre-load adjustment for the front suspension. The owners manual says to set it to 9.5 bar (11 psi), this must be a typo since 1 bar = approximately 14.5 psi. So should it be set at 138 psi?
Thanks,
Steve

it sounds like a typo in the manual - 9.5 bar is about 138 psi.

Hate to sound like a broken record, but the only source of reliable information would be Bob at Bimota Spirit. Mine came set by Bob perfectly for me (he knows my weight and riding style) so I never had an occasion to fiddle with mine. Dave

I just sent Bob an email. Since the bike I purchased had been sitting unridden in a collection for more than 2 years apparently the air had completely leaked out of the cylinder. I am looking for confirmation of the psi since I do not want to risk blowing a seal.

Do they use air or nitrogen?

Steve, if you need nitrogen, I keep a tank in the racecar trailer (for tires & shock canisters). I live about 15 minutes from you, and you're welcome to stop by sometime (whether you need nitrogen or not!).

Although it's apart right now, my Tesi 1Dsr might interest you anyway.

138 psi sounds about right. The front Extremetech "rod through" monoshock is very similar to the rear air shocks used on full suspension mountain bikes, which regularly run pressures up to 200 psi.

For reference, check out the Fox Float MXR rear shock for mini bikes:
http://service.foxracingshox.com/powersports/index.htm (click on PRODUCT SETUP SHEETS and then FLOAT MXR and then MXR SETUP SHEET). The instructions say to pressure the shock to 250 psi!

To get the Extremetech front shock up to pressure, you will need a high pressure shock pump as used on mountain bikes: http://www.universalcycles.com/shopp...p?category=133

Hope that helps. Let us know how you get on!

Thanks for all of the replies. Bruce I appreciate the offer. The manual says air however I would still like to take you up on the offer to see your Tesi.

froryde, thanks for the advice. I just purchased this http://cgi.ebay.com/ebaymotors/ws/eB...K%3AMEWNX%3AIT

Here is Bob's response.

9.5 bar is correct, so is 1 bar=14.5psi, I have to believe that the Italian engineers are better at arithmetic than that, so I assume that it was a typographical error, so 138 psi, which is quite high - also note, that they specify that pressure with the shock UNLOADED.
