Motorcycle News - This Isle of Man 900 SS is the definitive Ducati restomod
In the Ducati world, if you live in Europe and know your stuff, the name Harné Heuvelman is likely to be on your list. With the help of his son, Harné runs the workshop Back To Classics in the western Netherlands—and he can rebuild, redesign and remanufacture anything you need for a Borgo Panigale classic.
Wynne sent the cylinder heads to NCR for a performance boost and conversion to twin-spark ignition. He also reinforced the frame around the headstock, fitted a new swingarm designed for longer suspension travel, and installed a set of (very early) Öhlins rear shocks.
Harné’s client raced the bike throughout the 1980s and early 90s, and then parked it up in his shed for 20 years. “Then he decided to have the Ducati brought back to its former glory,” Harné tells us.
The engine rebuild was a little trickier. “The bike had spent a lot of time on the racetrack, and many parts needed extra attention and in some cases replacement.”
The NCR-tuned cylinder heads were rebuilt, and tuned and flowed still further. A new exhaust system was made up from steel tube, and ceramic-coated inside and out.
“The rear Öhlins shocks were originally fitted in 1978,” says Harné. “We found out that Öhlins started up the same year, so these are very early units made by this company. We of course restored and rebuilt them completely.”
The aluminum fuel tank is the original too, but with the dents removed. The seat is an original brought back to its former glory, but the fenders and front fairing are new items.
“We could have gone for a racing gearbox with different ratios, but decided not to—given the owner’s desire to be able to ride on the road as well.”
There’s now a bolt-on side stand, a Motogadget rev counter with digital speedometer readout, a tiny horn, and lighting.
At forty years old, this Ducati TT icon is now in the prime of its life.
Thank goodness there are still people like Harné Heuvelman and his son in this world.
