Engine was rebuilt at 32000 due to engine viberation. caused by a big end bearing. I sent the crank and cylinders to Ben fox performance for balancing and fitting new Pistal pistons. Tear down and re-assembly was done by me. Former aircraft mechanic. I bought this bike new on my 60th birthday and have been the only person to have ridden it. Ever! I can only agree to all the beautiful things written about this machine. I just don't ride it anymore and it belongs on the road or track. As far as accessories. It has the aftermarket Termignoni Titanium full exhaust with performance Ducati ECU and power Commander. Have Dyno sheet. showing 158. 7 at the wheel. Also has Sato rear sets. Pazzo short levers. Billet black fuel cap and the Michelin Road Pilot2 s are in good condition. 520 chain conversion.
