How do you tell a WIDECASE vs NARROWCASE single engine?

Post by BevHevSteve » Wed Jan 24, 2007 12:14 pm

How doyou easily tell the difference between a 'widecase' ducati single and a 'narrowcase' ducati singles??? It is easy, look at the engine mounting bolts..... This is the easiest way to spot the difference as they are different. John Collier filled us in with the following notes:

According to the parts books

* Widecase engine mount bolts are;
Rear 8 mm x 226 mm
Front 8 mm x 100 mm

* Narrowcase engine mount bolts are;
Rear and Front 8 mm x 85 mm

I drilled mine out to 3/8 and used grade 1o bolts with nylocks. My bolts were longer as I also used thicker front plates and the top rear mount to secure a clutch cable anchor.

The crankcase on a NC has 7 fins while the WC has 8. I don't have a WC Duc to validate my claim, but ancient Ducati legend has stuck itself inside my brain. True?
