Road Racing Series - Part 8

Does the bodywork come primed and ready to paint or will you have to do the final prep work yourself? Are the panels pre-drilled and, if so, will they fit? If they're not, you'll have to temporarily mount the fairing, mark the holes and then remove it for drilling (measure twice, drill once). For our build, our bodywork was supplied by Sharkskinz, the pieces came pre-drilled, primed and fit perfectly.

"Bodywork is one of a racer’s biggest investments..."

How you attach bodywork is crucial. The lower part of your fairing that serves as an oil catch pan will have to be removed every time you get a tech inspection. Other parts will have to be removed quickly to make repairs and to fix or replace crash damage. OEM-style screws won't do. Quarter-turn fasteners, like the famous Dzus (pronounced "zeus") design will do the trick. Dzus fasteners require you to replace the threaded tab on your frame (usually a slip-on design) with their tab. The fasteners are permanently affixed to the bodywork.

Once you remove your headlight you're probably left with an empty "bucket" that also serves as a fairing stay and a mount for the gauge cluster. An aftermarket fairing stay sheds weight and is more durable in case of a crash. The aluminum Vortex unit that we used had a provision for only the tach, doing away with the Ducati's speedometer and "idiot" lights.

Once you've got your bodywork on, you can choose to keep that raw test bike look of primer or have it painted for a more durable finish and a professional look. Unless you have professional equipment and a paint booth, the price of paint is worth the investment of paying a professional painter to apply it. Be careful when you decide on a local paint shop. Painting fiberglass is somewhat of a specialty and not something that all auto body shops know how to do.

Call it lack of creativity or call it love for the original all red Ducati paint scheme, but I chose to make the bike look as close to the original street machine as possible. Since I wouldn't be painting the tank or airbox panels I needed to make sure the fairing paint would match exactly. I'd tried to match paints before at the local automotive paint supply stores with less than satisfactory results. If you want a perfect match you have to go with Color Rite brand. The company has a relationship with major OEMs, which means their paint isn’t just close to the original color, it's identical.

Color Rite stepped up to the plate, supplying us with an OEM-matched "Italian Red" paint along with their recommended thinners and hardeners. Since the Sharkskinz bodywork comes pre-primed, the only prep work I had to do was a light scuff sanding, and then the pieces were off to the painter. A week later I picked up the perfectly color-matched set.

Color Rite also supplied color-matched paint for the frame and wheels and original Ducati white to paint on permanent "expert" number plates that would be hidden under the stick-on vinyl amateur plates.

Stock sportbike windscreens are mainly for looks and afford little wind protection to the average-sized rider. Racers may opt to replace the stock screen with a lighter and taller model that will give them something to tuck in behind on the long straights. We installed a tall "Corse" windscreen from Fast by Ferracci.

When you get your racing license, you will be assigned a number that must be displayed prominently on your motorcycle. Your racing organization will tell you where your numbers need to be. You can have the numbers painted on when you have your fairing painted for a clean, professional look or they can be put on with a yellow vinyl backing and black stick-on numbers. I opted for the latter, hoping that my "novice" status, as designated by the yellow backing, would soon be replaced with "expert" white.

Official lap times are gathered through a bike-mounted transmitter that registers each time you cross the start/finish line. The units themselves are supplied by the sanctioning body at every event and returned when the weekend is over. The mounts or pouches that attach the transmitters to your bike can be purchased from the tech inspectors at your first race. Place your transmitter where it will be protected in the case of a crash, but where it can be visually inspected to make sure the transmitter is on and in place before you take to the track.

Frame

The 748 was available in both a "Monoposto" solo seat and a "Biposto" dual-seat version. More than just a solo seat, the Monoposto version uses a completely different rear end with an aluminum subframe. I found someone on the internet who had a solo-seat bike and was interested in my dual-seat version, so we swapped. The different frame also required changing the rear portion of the wiring harness to match.

Although most other brands of motorcycles don't come from the factory with different versions of their rear subframe, lightened aftermarket subframes for racing applications are available.

Fit

Though I left "fit" for near the end of my priority list, it's one of the most important things on a race bike. A bike that is uncomfortable to ride is a bike that is hard to ride and will cause fatigue early on in a race. But many fit issues can be addressed without spending a lot of money.

Racers should take the time to adjust clip-ons, hand and foot levers and footpegs to fit their bodies. Sit on your machine in you racing gear and see where your hands and feet naturally fall. Try and adjust the controls accordingly. If you can't afford to add rear-sets, you should at least change the footpegs from the flat serrated-on-one-side OEM design to a round peg that is knurled across its entire surface to give you grip no matter where your feet are positioned as you hang off the bike.

But the range of adjustability (if any) on most stock motorcycles will not accommodate all riders. When a rider runs out of adjustment they need to go to aftermarket clip-ons, rear-sets and levers.

Clip-ons can change the angle and drop of the stock bars. They tend to be heavier-duty and more likely to survive a crash than stock bars. The Speedy Moto clip-ons we installed allowed for a wide range of adjustability in all directions and also had a provision to mount our remote master cylinder reservoirs.

Rearsets do just that. They move the footpeg position further back and higher for increased ground clearance and a more aggressive riding position. Most rearsets have a range of adjustability so the pegs can be tailored to fit the rider. The footpeg mounts don't fold up like OEM pegs to add to crash protection. In case of a crash, individual pieces can be replaced so the whole unit isn't scrap. I installed a set of Woodcraft CFM rearsets. They are machined from billet aluminum for light weight and durability. Fit is excellent and close tolerances negate the "slop" that the OEM shifter had. As mentioned before, most rearsets come with the pieces necessary to convert your shift pattern to GP style.

The stock Ducati Brembo levers are adjustable, as were the Brembo radial units that replaced them. Adjustable levers don't just accommodate a rider's hands, they can also adjust the clutch pull or amount of feel a front brake has if you're riding on a rainy surface or as your pads wear. The Brembo units allow for this to be done with a gloved hand "on the fly." Even if you're running stock master cylinders, it's worth it to purchase aftermarket adjustable levers.

The seat on a race motorcycle is not designed for comfort, because you're not going to be spending a lot of time in it. It is most important that the seat surface is smooth without edges or welts so that a racer can slide across it as they move their body around the bike.

The Sharkskinz bodywork can be ordered with a provision for the stock seat or a foam pad. We opted for the foam pad, to save weight. The foam can also be layered or cut down to fit the rider's style. Its smooth surface allows for your leathers to slide from side to side as you transition your body.

Racing leathers tend to be slick, and if you can't grip the painted surface of the tank with your knees, a last-marker braking maneuver is sure to send your most sensitive of body parts on a blind date with the gas tank. Being able to support your weight by gripping the tank with your knees is also crucial to prevent fatigue in the wrists and to keep a rider from overloading the front end with their body weight.

Stomp Designs is a company that got its start in the extreme sports business, making grip pads for surf and snowboards. When they branched out into the two-wheeled arena, they quickly came up with one of the best designs available. The Stomp Grip pads are custom-sized for individual bikes or they can be ordered in a cut-to-size universal sheet. They stick onto the metal or plastic of a tank with 3M backing. The pre-cut units we were supplied with fit perfectly and applied easily, putting a grippy surface right where your knees contact the tank.

The Slick, the Sick and the Trick: Road Racing Bling

If you spend time leafing through the pages of a performance catalog like Lockhart Phillips you'll be overwhelmed by the variety of parts and accessories, billet this, titanium that, and how quickly they could break the bank account of a newbie racer. There are plenty of other parts that won't make you faster but will make your bike function better on and off the track. As you become a better rider, saving weight will become more important. These parts aren't only lighter and sexier, they're more durable and will last longer under the stress that racing puts on all of a machine's components.

When it comes to the Ducati 748-998 series of motorcycles, the go-to trick part specialists are Mad Duc, a small company out of Sun Valley, CA. They supplied us with several of their billet aluminum anodized parts, including a rear brake caliper mount, ride-height adjuster, rear axle nuts and a rear sprocket hub for lighter weight and better durability.

One of the most practical parts that Mad Duc supplied us with is their "keyless" conversion. There's nothing like trying to keep up with a set of keys while wrenching on a bike at the track. Mad Duc offers a toggle switch that replaces the bulky, stock ignition key. A screw-on gas cap makes for easy access to the fuel tank for between session re-fills. The last piece of this system is a machined "button" that replaces the key tumbler on the seat latch mechanism. This allows you to use Ducati's original hinging and locking rear tailsection system without having to use a key.

After we completed all our modifications, it was time to take the bike to have the Power Commander zeroed in on a local dealer’s dyno. While the 748 was on the truck, I put it on the scales to check its post-build weight. Months ago I had weighed the stock machine with half a tank of fuel, and it tipped the scales at 460 lbs. In racing trim it was down to 420 lbs. The modifications and removal of stock equipment had shed nearly 9% of the 748’s original weight. I think I have a new motorcycle.
