Description

1977 Yamaha RD425 This sporty little beast was built by Rusty Bolt Garage in Santa Fe. NM and is a barrel of fun to ride. So much fun it makes you wanna slap yo mama! Though. we have been taking it a little easy on her since she just had a fresh rebuild on the motor. We also upgraded the suspension. brakes. electronics and controls. Come to think of it. we either upgraded. replaced. or repaired everything on this baby! We wanted to build a unique and fun bike to ride while still maintaining some of what we consider true 'RD spirit'. With many custom pieces made of fiberglass or aluminum. not only does it run great but shes quite a bit lighter too. They definitely wont be able to keep up and only way they will be able to find you is to follow that little trail of blue two-stroke perfume down the road. Head over to PipeBurn. com to check out their feature.  Also featured on riceburner. org. wind-blown. com. torchgirls. com. caferacernews. com. and on the Yamaha Motors USA page.  We made a couple of changes after the photos were taken. the first was swapping out the pod filters for the Y-boot and a single Uni Pod filter. the second being moving the speed sensor and line to the right side of the front tire so the wire could run with the front brake line. Here is a short video of a cold start on the bike. Here is a short video of the bike running after it has warmed up.

This included a bore to 66mm. with new pistons. rings. pins. and bearings. New gaskets. seals. o-rings and bearings throughout ensure smooth operation and  no leaks. The heads and cylinders where thoroughly cleaned by Vapor Blast Solutions here in Santa Fe. then the heads where treated to a nice polish.  The cases and cylinders got a fresh coat of black and the fins were sanded to match the wheels.   Frame and Swingarm-  Before being powder coated in satin black. the frame had all unnecessary tabs and bracket removed. as well as a new electronics tray to hold the reworked wiring harness and the. now hidden. oil tank which sits neatly tucked under the seat. A new upswept rear hoop was fitted to provide clearance for the rear tire and allow the hidden taillight/brake light/ and turnsignals to be seen when the bike is in operation. The swingarm was treated to a fresh coat of black powder coat as well as new bronze swingarm bushings and new inner bushings. Suspension- The front forks were rebuilt with new springs from RaceTech and some handy fork caps with built in preload adjusters so you can tune the suspension to the riders needs. New seals and dust boots were installed after the tubes got a good polishing. In the rear we installed new Assault shocks that are . 5 in longer than stock. That. coupled with dropping the front . 75 in. will put a bit more weight on the front wheel allowing for better handling and control when accelerating out of corners and from stops. Intake. Exhaust. and Lubrication- The stock Mikuni carburetors were used after a complete teardown and cleaning again by vapor blasting. All brass and gaskets where replaced with new items and adjusted to accommodate new DG performance expansion chambers and a single pod Uni filter and Y-boot where fitted. We stuck with the Yamaha 'Auto Lube' system so you wont have to worry about running any premix. but gave the oil pump a fresh rebuild and new lines and hoses. Lighting. Controls. and Gauges- Gone are most (or all) of the stock items. We started by replacing the headlight with a newer LED unit that flows more with the angles of the tank and seat. while the lens shape mimics the blocks and knee pads on the tank. We decided to use rubber mounts for the headlight to absorb vibrations rather than make solid brackets so your bulbs last longer. Small but super bright LEDs handle the turn signal duty up front and a combination running light/brake light/ turn signal unit that is neatly hidden under the seat in back. Sitting on a new low rise handlebar are new grips. left and right control switches. and new adjustable aluminum clutch and brake levers anodized in black. Aluminum rear sets from KamiKaze Moto were fitted where passenger pegs once lived. With the rearsets in mind. we also reworked the kickstart lever for plenty of space. Handling all the gauge duties is a new Koso unit that is rubber mounted and held in place by a bracket fabricated in house. We also relocated the key switch under the tank to further clean up the cockpit. Powering everything is a new featherweight battery. Body. Tank. and Seat-  We stuck with the original RD tank but had custom blocks and knee pads cut. We like old style decals that you see on many RD's but wanted something unique. The seat was made in house and is a one of a kind fiberglass piece that follows the lines of the headlight and tank. The pad is Ultragel cut to fit the pan and was upolstered by B&M Upholstery in Santa Fe. The benefit of using the gel is that is absorbs vibrations. which is especially good on 2-stroke motorcycles.  The front fender has been cut down but left in place to help support the forks. in the rear we removed the stock fender and added an inner fender that matches the front. The fenders were powder coated in satin black to match the frame while the tank. seat. and headlight were treated to a  Ford color "Toreador Red'. Brakes. Wheels. and Tires- We installed new master cylinders as well as new reproduction brake calipers on both the front and rear. We then set the rotors up on a CNC machine to drill and countersink them to help keep brake temperatures down. Lower temps means better stopping power. New custom stainless steel brake lines where also installed to once again aid in stopping power and brake feel. The wheels where coated in black and had the fins sanded to match the cylinders. New modern compound tires complete the package giving great traction in the corners and when stopping. **Some extras for the buyer include an extra set of keys. an extra set of spark plugs. some different jet sizes. an extra set of exhaust gaskets. a replacement bulb for the front turn signals. the manual for the Koso gauge. decals. a set of brake pads with anti chatter shims. and a set of anti vibration bar end weights.
