►More Testimonials

The days of Legends and Heros. Off Road Motorcycling was better back in the day! Right? Until we ride those bikes again and realize just how poor their suspension and brakes were... From the 60s thru 80s Suspension and Brakes were not up to the demands of harsh terrain, jumps, moto-x tracks, engine power and rider performance demands. Race Tech has solutions for most models. Race Tech upgrades can bring your vintage motorcycle suspension performance up to modern standards.

RT Hi-Performance Springs are extremely lightweight and the first important step to a proper setup. Gold Valve Emulator Kits for Forks are designed to offer the damping characteristics of modern cartridge forks. They provide personalized setup with easy adjust ability that provide significantly better flow, a more consistent plush feel with increased bottoming resistance.

G3-S Custom Series Shocks provide a personalized setup as well as a choice of features and colors with guaranteed performance. Plus like all Race Tech products they are made in the USA! 

Brake Arcing service optimizes Drum Brake Performance with greatly improved stopping power, feedback and firm feel at the brake lever. Don't overlook this surprising service!

GOLD VALVE CONVERSION for MONOSHOCKS

 


Most 70s & 80s OEM Vintage Monoshocks are rebuildable. Many of the late 70s thru 80s shocks had poor quality valving systems. We have figured out a way to fit the latest technology Gold Valves on most vintage shocks. You will be amazed - guaranteed! 

Another benefit of this process is the shock receives a full service rebuild, too often overlooked and critical to proper performance and shock like even with stock settings.

Race Tech will service most OEM and aftermarket shocks. Regardless of brand, we have most rebuild parts in stock as well as spring upgrade options.

Hard Anodizing is also available and desperately needed process for vintage shocks.

 FORK TUBE REPAIR - RECHROME SERVICE for VINTAGE MOTORCYCLES 

Ship Suspension to  Race Tech.for Service

If replacement fork tubes for Vintage motorcycles are not available it is often possible to repair them. If damage is limited to worn chrome, rust, minor pitting and the Fork Tube is not badly bent repair is an option. This service trues the tube, grinds off the old chrome, rust and pitting then builds fork tube back up to spec with high quality industrial Hard Chrome. 

Please note not all tubes can be repaired. Tubes badly bent or with deep pitting care beyond this service. Thick wall tubes 30-41mm can generally be repaired. Thin wall 41mm and larger tubes typically cannot as there is not enough material to allow the repair 

 Rust is Repairable in most cases however Tubes Bent to a Crease are Not

HARD ANODIZING for FORK SLIDERS and SHOCK BODY

Fork Sliders on Vintage and Classic Models are not hard coated. In fact most do not even have fork bushings. The results are high friction, high wear and rapid oil contamination from aluminum due to the chrome fork tube working directly against the uncoated aluminium slider.  Hard Anodizing is strongly recommended for Vintage and Classic Forks!

 

Fork Slider and Shock Body Hard Anodizing

Hard Anodizing is a coating used on modern forks that can be applied to most fork sliders to reduce friction and wear. The outward appearance is a matte black look similar to black late model fork. This process is also available for shock bodies provided the shock is rebuildable.

Hard Anodizing Benefits

Excellent resistance to wear
- Hardness provides reduced friction

More info about Hard Anodizing
Powder Coating of Fork Sliders is also available for top grade cosmetic appearance.        

Get the best of both performance and appearance by having your fork sliders both hard anodized and powder coated! 

BRAKE ARCING  for DRUM BRAKES

 

 

Brakes are one of the weak links of Vintage Motorcycles. Weak stopping power and spongy lever feel are common complaints of vintage drum brakes. This can be remedied with Race Tech Brake Arcing Service. With the popularity of drum brakes on vintage motorcycle builds as well as vintage race rules requiring the use of drum brakes this service is a big advantage. For the racer lap times improve, for the street rider safety improves. After all, whether you are facing turn one a little too hot or you are facing a left turning SUV, stopping power becomes everything! Add improved braking to your Race Tech Suspension to complete your vintage motorcycle upgrade! 

The difference between winning and losing often comes down to braking. Most drum brakes are mushy with poor stopping power. Race Tech is now offering Brake Drum Turning and Brake Shoe Arcing to improve stopping power tremendously. Race Tech Brake Arc Service is superior as we first cut the drum flat and round then arc the shoes to the exact drum diameter with the shoes mounted on the backing plate.  ►More Info

Vintage Short Travel 

Short travel suspension models are very compromised and need the most help. Fork Spring upgrades are a must and Gold Valve Emulators take the harshness out of the forks while offering adjustability the rider can tune quickly and easily to suit their riding type and preferred feel.

The OEM shocks on these bikes may or may not be serviceable. Even if they are better performance at a better value can be achieved with G3-S Shocks. We do offer full rebuild service along with spring upgrades and Gold Valve options for Vintage Öhlins Shocks as well as Works Performance Shocks. Contact us for details

Post Vintage and Evolution MX

Late 70s through 80s models had good sized 38 and 43mm forks with decent shocks offering long travel. What they lacked was proper settings. Step 1 is to replace the overly soft fork springs with RT HI-Performance Springs. On air assist forks this eliminates the need to run air. Gold Valve Emulators smooth out harshness, improve bottoming resistance and offer easy adjustability to suit rider preference.

Shocks on this generation are fully rebuildable responding exceptionally well to Gold Valves and Race Tech Spring. Many riders enjoy racing against late model bikes when fully Race Tech equipped!

Many Post Vintage and Evolution models have drum brakes that lack the stopping power these bikes need. Send in your drum brakes for our Brake Arc Service for dramatic improvements in stopping power!

HUSQVARANA PISTON RINGS

 

 Husky Piston Rings

VINTAGE HUSQVARNA FORK PARTS

Early Husky forks, 35 and 40mm have a common problem with the piston bands. The stock Piston Bands are usually worn out and are known to break. Since these parts are now obsolete from the factory we have produced a hi-performance replacement bands for both the 35 (FPPR HQ35) and 40mm (FPPR HQ40) forks.

35mm – FPPR HQ35 – Add to cart
40mm – FPPR HQ40 – Add to cart

We also have special Emulator Adapters for both of these forks NOW available. The performance difference with Emulators is huge! ►More info about how these forks work!

*Note - On 35mm fork caps we have special copper washers (HMWC 3035) that seal perfectly. The stock 35mm forks don't have anything to seal them (plumbers tape doesn't work well on straight threads). This is a really clean solution.

MAICO 36mm EXTERNAL SPRING FORKS

  

FEGV 3601 Maico 36mm Fork Gold Valves

Early Maico 36mm Forks require a unique Gold Valve Emulator design that threads onto the damping rod. The stock piston assembly is replaced by the Emulator resulting in greatly improved damping and adjustability.
