Taking a break from race-preparing RM-Z450 and RM-Z250 machines for use in European supercross championships - including the UK's Arenacross series - SR75 Suzuki team boss Geoff Walker has breathed life into an RM250, using genuine Suzuki parts and a smattering of performance goodness from team sponsors.
"The donor bike was a 2005 RM 250, but it was fairly beaten up when we got hold of it," Walker explains. "But we got it in and stripped it right down. Every component was inspected, and then either cleaned up and refurbished or replaced where necessary.
"The plan was always to turn it into a stunning example of a fire-breathing race machine, and the result comes after many hours of cleaning, metal-working, and rebuilding. It uses genuine Suzuki parts - many of which are still available from new from Suzuki GB - and the best aftermarket performance parts available."
At the heart of the build is the 249cc single cylinder engine, which was fully rebuilt with genuine Suzuki spares, including crank, piston, gaskets, seals, and bearings. It was then treated to a Hinson clutch and V-Force reed valve, with a fresh dollop of Motul keeping everything lubricated. An FMF Racing ‘Fatty’ exhaust helps it breathe, hoses come courtesy of Samco.
The freshly rebuilt engine puts its power to a new Talon back wheel via Mika Metals chain and sprockets. A matching Talon front rim is mated to an oversized brake disc and new genuine Suzuki brake lines ensure strong stopping power. The new Talons also sport fresh Pirelli MX32 rubber.
More genuine Suzuki parts helped return the chassis to full working order, with all swingarm and linkage bearings replaced. It is now suspended by Factory A Kit SHOWA HRS Suspension at the front and rear.
Mika Metals also supply new handlebars and grips, while the rider stands on RM-Z450 pegs, modified in-house to fit. When sat, the rider's pants grace a seat that features 15mm taller foam from Docwob Imports and is finished in a Motoseat ribbed cover, built to SR75 specification.
The finished package is wrapped in a Polisport RM250 ‘restyle’ plastics kit, set off by a GP Grafix custom Team SR75 replica graphics kit.
So where will we see it?
"Who knows?" Walker muses, although you get the impression he has a plan and knows more than he's letting on. "I know we can't wait to see this beauty on the track at some point, but we may have to show it off as it is a few times first.
"What is for sure is I think we've built one of the coolest dirt bikes on the planet. It's always fun to work with Suzuki GB on fun projects such as this which have an amazing, nostalgic feeling surrounding them.
"But you never know, maybe this beauty will appear at an Arenacross or European supercross meeting event next year."
