The Commonwealth Motorcycles Ducati Diavel Turbo


The Ducati Diavel is already one fast performance cruiser scoot but the folks at Commonwealth motorcycles wanted a winter project and ……. well, wouldn’t it be better with a turbocharger?


Why choose the Diavel. “Easy” says Chad Wells, Commonwealth’s Service Manager.

“…because it is so damn cool! I think the styling is gorgeous, the design and overall appearance for a sport cruiser is superb. The classic Ducati single sided swing-arm, machined wheels, matching machined rotors, etc….. With the mufflers gone we were able to open up the whole right hand side of the bike. You see the beefy swing arm and all of the killer looking wheel now. It just showcases what Ducati had hidden behind humdrum mufflers. “

Another reason to do a turbocharger conversion on the Ducati Diavel is because, to date, nobody else has!

“I planned on being first one in the world to do this, and it looks like I am. I hope Ducati enthusiasts will enjoy it and be excited to see the finished product. I don’t think we will develop or sell kits, but you never know. We had been selling a few Diavels at the dealership and when I rode the bike, I fell in love…..but I felt like ther was something missing!”

With a long wheelbase and a big fat tire, the Diavel is probably uniquely suited to handling even more power than the stock Testastretta 11º kicks out since, unlike most other performance cruiser options, it has highly specialized suspension, wheels and brakes straight from the factory. On 8 lbs of boost, the turbo Diavel boasts 236bhp and 130 ft/lbs on pump fuel! There’s a word for that – plenty.”
