r0447 TricTrac Installation: Honda TRX450R
You have just purchased the most technically advanced a-arm on the market today. It shouldbe expected that this install will be difficult and possibly time consuming. Make sure you read thedirections carfully and call Houser Racing 1-877-6-GA-FAST for install questions.
First, try to understand how your a-arm works and what it will do for your riding.The TricTrac a-anns adjust your caster for you while the ATV is in motion. When you slow down for a tight turn, yourshocks compress from the decrease in acceleration. The TricTrac a-afin$ utiLize this compression by using the splineshaft to force the upper a-arfri forward. This forward movement of the upper a-afin is a decrease in caster. After thetight turn is completed and your ATV retums to ride height, your caster will automatically retum to its ride heightposition as well.
?What is the ideal ride height position of my upper a-arm (forward or backward)?--This position depends on what feels the best to you when you are riding. The TricTra, \a-afins are designed to have 14 different positions you can set during installation. This iswhy the install can be very time consuming. You should take yourATV out and ride it aftereverything is installed. See what you think and then take the upper a-arms offand make
