My daughter raced her 90 viper last year and did very good, but we are now looking for some performance and suspension mods. After surfing the internet for months and talking to local dealers my head is left spinning with no real answers to speak of. I am looking to get extended a arms, wider rear axle, and shocks to start with. I have heard that other make parts may fit but so far nobody has told me wich ones. Also looking for a pipe. Any help would be greatly appreciated!!!

 

Welcome to the forum.
Is the 90R the 4 stroke model?

 

Contact Kevin Herr at HJR Motors about engine mods, he is a 2 stroke master. You can look him up at herrjugsracing.com good luck

 

It is a two stroke. I think '01 with reverse. I guess I should run the serial and find out exactly!

 

thanks HMT, will check it out

 

I ran the Vin and it comes back as an '06 Viper RXL-90R

 

There are tons of mods out there for the motor.
