DMR has been profesionally tuning engines and preparing bikes for both trackday and racing use for 4 years with many race wins in all classes to our credit in both the UK and overseas. We offer the full range of engine building and tuning services from straight forward re-builds to full on 50cc open class race tuning on the entire range of bikes and engines. DMR has a fully equipped workshop with a lathe, milling machine, foredom porting tools, crankshaft re-building and truing jigs, a Dynapro S32 Chassis Dyno and uses both TSR and Engmod2T 2 stroke engine tuning and simulation software. DMR has a dyno chassis available for both UK and overseas customers requiring engine tuning. There are some dyno graphs displayed on the "Engine Tuning" and "Squish" pages of this site.
The “OR” H20 engine has many performance enhancing features over the alternative pocketbike engines. The inlet follows a shorter and straighter path in order to move the carburettor closer to the pipe signal. The increased width is there to accomodate the KO V Force reed cage as an optional bolt on upgrade. The race crankshaft is machined as a single piece web and fitted with tungsten and bagelite plugs for balance and inertia purposes. A range of pipe options are available for preferred power delivery purposes.
Below are a few samples of the KO, Lisci and SPS race accessories DMR offers. DMR offers the widest range of minimoto race products in the UK. There are many items, unique to DMR available, including the adjustable main jet for PHBG carburettors, water cooled crankcases for OR and BZM engines from SPS and the 28mm fork conversion for DM and GRC bikes from Lisci Racing.
DMR is based in Hull, East Yorkshire, UK. Contact details are shown at the foot of this page. Enjoy the site. (Page updated 7/10/09)
