Project Ducati 998 Superbike Part 3: Radiator, Fairings and Track Preparation
The 998 hose has to be trimmed to fit the 999 style radiator.


A quick trim is all that’s needed.

Sitting back proudly thinking how smart I was to do this instead of all those idiots that buy fancy $200 reservoirs, I decided to reinstall the airbox and inlet tubes that had to be removed to get the original reservoir out.

Here’s the new radiator with cap trying to occupy the same space as the right-hand intake runner.

The right side air inlet tube tries to occupy the exact same space as the new radiator cap. All my dealership memories came rushing back of flushing cooling systems on 848s and 1198s. They use the same 999 setup and the fit is so tight you can’t even remove the radiator cap because it hits the underside of the air inlet tube. I had the same problem, only worse because my air tube wouldn’t even fit. At this point, there’s no time to get another 998 style reservoir. I’d also need 998 radiator hoses before the weekend because I’ve cut mine because I’m a dumbass. Time to make this radiator fit.


  1. Love it! Man… you have a 675 track bike too?! I’ve been eye balling the Street Triple to replace my 600RR for the street bike, but I haven’t convinced my wife to let me keep the 600RR too for a track bike. I just know I can’t sell the 600RR before picking up a new bike or there will be 0 bikes in the garage and it’ll stay that way, ha!

    In my previous job,, I learned the hard way about o-ring material and compatibility with different types of fluids. Even different types of oils. Who knew that one type of oil would react differently than another type of oil?

    I found this site for material compatibility with all sorts of fluids:

    Most generic o-rings are EPDM. Which is probably what you have. I’d recommend stepping up to at least NBR (nitrile). FKM (Viton) is the baller stuff which is typically easy to get.

    1. I can’t recommend the street triple enough. It’s arguably more fun even on the track than a fully faired machine depending on the track. The first generation ‘R’ models are the absolute jam, and they’ve made basically the same bike for so long that they’re dirty cheap on the used market.

      The fuel pump o-ring was a real bummer. I ended up sourcing Viton replacements from McMasterCarr. They’re much less susceptible to ballooning up after seeing fuel. Newer Ducati’s use Viton, but they’re something like $50ea. Sourcing them 3rd party saves something like 70% of the cost.
