loudbike Ducati TT1 Race Exhaust / Ducati 2V Belt Drive Twins TT1, TT2, 750 F1 (modified) Many Ducati builders and riders who are reviving 750 F1s and TT1s have avoided using the classic NCR #7 and Montjuich cams – primarily due to the fact that if you try and silence them, they simply lose power and won’t make any torque at all. The big overlap and duration that make these old-school cams so much a part of the TT1 or F1 racing experience requires an open megaphone to get the spent gasses out of the motor in the very short time available – cork ‘em and that process goes to hell in a hand basket and that means that with the rapid disappearance of circuits that will allow us to run our machines as God (FabioTaglioni) intended, we drop in set of modern cams and suffer the indignity of a classic Ducati that sounds more like a lawnmower than a thoroughbred. Developed for F1 racers by Connecticut tuner and racer Mike Weber, the loudbike Ducati 750 F1 95db Race exhaust makes more torque and similar power to the open factory system with NCR #7s while staying under the 95db limit. To our collective knowledge no one’s been able to do that – and as a bonus it doesn’t look and sound half-bad either.. This system is a version of Ducati 750 F1 95db Race Exhaust developed for F1 racers by Connecticut tuner and racer Mike Weber - repackaged for use on the Ducati TT1 and TT2. Aside from reworking the primaries for fairing clearance, we added an extra step just to drop the secondary into the area usually cut-out to clear the factory megga and then worked on an exit angle that flowed with the overall lines of the rear of the machine. You'll also notice an additional hanger tab that will allow you to run a support hanger from the rear sub-frame (under the seat). It's got loads of ground clearance and only weighs in at 4Kg; which is excellent for a system that will get you into a track with a 95db sound limit while developing a bit more torque than the open factory system.. Using light-gauge, TIG-welded 304 stainless steel, these systems are carefully hand-crafted by Frederic Mignault and weigh a surprisingly low 4Kg and offer excellent ground clearance, fit and performance. Although the system was developed with the Ducati TT1 fairing and frame, it would be an excellent choice for a full-on 750 F1 racer where the lower frame section has been eliminated and the foot pegs relocated. You'll also get good performance with standard cams one this system, so it's an excellent all-around exhaust system where light weight, ground clearance and noise suppression are a requirement. IMPORTANT: These systems are built to order against limited production runs that we schedule every 3 weeks. This means that depending on where your order is in our cycle, order/shipment time can range from 1 to 4 weeks.

The Ducati TT1 and it's street-legal progeny, the Ducati 750 F1, have now gone on to become some of the most desirable and collectible models from
I’m a sucker for the endurance racer look, especially if twin headlamps are involved. And this is one of the best examples I’ve seen for a long time. It’s owned by Gregory Rathe, and there’s an interesting history behind it. In 1985, Ducati made a replica of its Pantah-based TT racers called the 750 F1. Around 1,500 were made, and won acclaim for their streamlined design and exceptional handling. This particular machine originally belonged to Lou Saif, the well-regarded restorer of TT2 and TT1 factory race bikes. “Being based in New York City, I’ve had the pleasure of getting to
Among many other things, Ducati is known worldwide nowadays for its trellis frame and belt-driven camshaft V-Twin engine, both of which owe their formation to the 1980 Pantah. The Pantah also formed the base of one of the greatest motorcycles of the 80s - the Ducati TT2 racer. The TT2 was an instant success, and…

With 88 rear wheel horsepower in a sub-300lb package, this example is arguably the quickest and best handling old-school 750cc TT1 in North America. I built this TT1 using period components as a relatively faithful replica of the TT1s that ran in the AMA BOTT GP class back in the day. The only deviation being the modern (90s) calipers and pumps, ignition coils and the non standard crankcase breather box in the seat. However, it differs from most TT1 replicas in that it was built to be a fast and reliable track bike. Over the years I’ve found that the only TT1 frame that seems to work well with modern 17” wheels & slicks is the final series Verlicchi large diameter, thin wall. Back in the day, Reno Leoni had DM Frames make a copy of the Verlicchi and DM has since modified the jig to allow for the use of a big block motor. The DM version was checked digitally last year against the Verlicchi and they are geometrically identical, however the DM is 12mm longer between the upper cross brace and the steering head. I countered this somewhat with the offset on my triple clamps, but the small difference in trail gives the DM a bit more stability with a very small decrease in agility. The whole thing is held together with over $900 in titanium and aluminum fasteners. Every bearing and seal in the motor and on the machine is new. The bike is a highly-developed example of an old-school TT1 – works brilliantly on the track and handles better than any TT1 I’ve ridden. The bike and motor were built with care and a high level of attention to detail over an 18 month period. It was broken in correctly on the dyno and then saw six horsepower/tuning pulls and roughly 4.5 hours of track time. I’ve run the bike at Calabogie and Mosport – and came away delighted with the performance and handling on both occasions.

In 1981, Ducati unveiled a gorgeous racing twin based on the successful Pantah. The TT2 used a Verlicchi-designed frame with a steel cantilever swing-arm, Marzocchi 35 mm forks and 18” magnesium wheels. The machine we’ve got here is even better: a thorough upgrade built for Spaniard Joan Antoni Fontquerni. He’s transformed his '82 model into a lean, sinewy racer with heart-stopping looks. The forks have been swapped for beefier Marzocchi M1Rs, and the wheels are now 17”.Fontquerni has boosted the original 600cc motor to 750cc, with a new crankshaft, bigger cylinders and pistons. He’s also fitted a new exhaust system
Absolutely stunning TT1 loaded with all the correct impossible to find period race goodies including a 750CC F1 race engine built up on a set of 750 crank cases, race cams and pistons, Malossi PHM 41's, Campagnolo wheels, magnesium rear caliper carrier, period race quick release Brembo calipers, period Brembo race clutch cylinder, Brembo PS 19 adjustable radial front master cylinder, magnesium dry clutch and all built to a very high standard. #Desmo #Ducati #19811990 #701800c
