VINTAGE RACING - STREET - CAFÉ RACER - CLASSIC MOTORCYCLES

 

"Race Tech did their magic on the stock forks of my 1973 Kawasaki Z1 and truly made it a different motorcycle." - "Big Al" Madril, Clovis, CA

►More Testimonials

While engine power and development surged on motorcycles thru the 1960s and 80s, suspension and braking development fell behind leaving machines that struggled to meet the performance demands and comfort needs of their riders.  Race Tech has used modern R&D to fine tune forks, shocks, and drum brakes for most models providing top of the line modern feeling suspension for your vintage motorcycle.  

WE GUARANTEE IT!

Race Tech specializes in personalized suspension solutions to smooth out your ride.  Browse through an overview of Race Tech's products and services below and be sure to check out our Product Search to see what we offer for your motorcycle.

Great suspension comfort, safety and handling is just as important for the Street Rider facing the urban jungle or cross country trek as it is for the Racer!

HI-PERFORMANCE SPRINGS

 

"I'm really happy with the ride over light ripples and hard bumps. I went over that concrete runoff on top of the hill at Barber, just before the hard right museum turn with no problems with the bike getting upset. Other people swore they wouldn't go over it ever again. They must not have the kind of good suspension tuning we have worked out on their bikes..." 

- Wick Wilkinson, Thruxton 81x

G3-S CUSTOM SERIES DUAL SHOCKS for VINTAGE

 

 

 "I chose Race Tech for my AHRMA 350 Sportsman and it really works! Matt guided me on choices and performed a complete fork conversion. We hard anodized it along with Gold Valves and Custom Fork Springs. The black and red G3-S shocks work even better than they look! I was not sure of having Brake Arc was really worthwhile but WOW was it! My Race Tech setup put me on the podium my very first ever AHRMA race weekend!."

- John Miller, Tennesee

HARD ANODIZING - FORK SLIDERS

 

 

 

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

 

Fork Slider & 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 type.

Hard Anodizing Benefits:

- Excellent resistance to wear
- Hardness provides reduced friction
- Improved oil life

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! 

DRUM BRAKE ARCING 

 

 

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

TECH TIP - FLOATING BRAKES

 

 

 

Floating Rear Brake maintenance is commonly overlooked and can have a severe impact on suspension and handling. This type of rear brake was common through the 80s on both dirt and street/road race bikes. ►Read More

TWO STROKE MOTORCYCLES

 

Perhaps the most iconic of 70's Japanese motorcycles were the lightweight Two Stroke machines. These giant killers were often humiliating bikes of much larger displacement on the street or the track. They helped coin the term 'Squid' in the California Canyons back in the day.

Kawasaki Triples are a handful, bring them under control with desperately needed fork upgrade. G3-S Shocks can be made to any length and adding 1" to the stock length will help make the Kawi H2 handle like it should! 

Suzuki GT Series respond very will to proper fork spring rates and Emulators. G3-S shocks dropped seconds off lap times on AHRMA GT550 Road Racer. Have an RG500? We have suspension solutions!

Yamaha RD's and RZ's were among the best handing bikes of their day yet they feel soft and squishy by today's standards but we can fix that! We have fork kits specifically for the 34mm KYB forks and G3-S Shocks for a balanced setup. From '73 RD250 to '85 RZ500 Spring and Gold Valve options are available.

Kits for Betor, Ceriani and Marzocchi Forks are available for European models, see 'Vintage Fork' listings in Product Search  

Many early models sported drum brakes that lack the stopping power these bikes need, send in your drum brakes for Brake Arc Service for dramatic improvements in stopping power!

Imagine how much better your ring-ding could be with proper suspension and brakes! 

FOUR STROKE MOTORCYCLES

 

The growl of a Triumph Twin or the howl of a GS1000 both are music in motion for the vintage enthusiasts. Big bore four strokes were defined by Japanese models of the 70s and 80s along with European bikes from BMW, Ducati and Laverda. These fast, heavy machines put a high demands on their suspension, typically overwhelming it. Race Tech can address these short-comings, greatly improving handling and comfort. 

Honda CB550/750/900 defined the class for Japanese bikes in the 70s and then there was the CBX. The Honda models handed well in their day, modernize them with Race Tech upgrades!

Kawasaki brought power to the table the the Z900 and Z1000 models that, much like their two stroke predecessors, went faster than the stock suspension could cope with. We can fix that!

Suzuki brought balance with the GS550/750/1000/1100 in the late 70s. The GS series bikes handled well back then but by today's standards, not really. Proper Fork Springs, Emulators and G3-S shocks change the game making the GS bikes really handle!

Yamaha SECA models of the 80s suffered from extremely soft suspension, firm them up with Race Tech forks and G3-S Shocks. XJ550/650/750/900 as well as FJ & FZ models applications available as well 

BMW Air Head models are one of our most popular applications. Full Fork Upgrades as well as TNK Fork Tubes are available for the front, G3-S for the rear. Check out the Rider Magazine R75/6 review 

BSA and Triumph models '71 on with aluminum slider forks such as T120/T140/T160 respond very will to Race Tech Springs and Gold Valves  and those forks can really use the help. Brake Arcing can make big improvements in stopping power.

Laverda Jota, Mirage and RGS models are not overlooked! Check out Laverda Mania Special Thank You to Scott Potter & Moto-Laverda
