TDR Scooters |
|
Can offer a range of sevices from the supply of well known brand tuning parts and engine building to specialist one off fabrications and complete scooter conversions
One of our specialities is the design and fabrication of two stroke expansion chambers for any model including custom builds where there simply is`nt an exhaust available
|
|
On this page you will find some examples of our work
|
|
|
|
A one-off expansion chamber for a customer, he fitted the Kawasaki KX500 engine to a RMZ 4 stroke moto-cross frame and found that no exhaust on the market would fit. We created this wrap around chamber to keep the tuned length correct for the relitively low revving KX engine
|
|
One of Dave Briggs Gilera runner twin engine conversions, as well as the exhausts we also designed and fabricated a pair of reed block housings amd manifolds for the oversize reed valves
|
|
Another Lambretta Auto conversion

This time the owner/builder wanted a performance exhaust to match the characteristics of the auto engine
but to look like a traditional Lambretta race exhaust.

Another twin pipe construction this time on a liquid cooled engine built by Marsh
|
|
|
|
Con-air and Mental Elf were two of our Aerox 172 projects mating a tuned Gilera Runner 125cc with the Yamaha Aerox 50cc rolling chassis,a lively combination
One of the more unusual commissions we have recently undertaken is the construction of four expansion chambers for a twin engined sidecar outfit powered by two Italjet Formula 125 twin engines.
Another one -off exhaust construction, this time a Vespa Small Frame with a twist. . . it`s running a reversed cylinder from a Rotax Aprilia powervalve 125. One of the most challenging builds to date due to the dimension of the exhaust nesseccary for it to perform but the very limited space available.
