Yoshimura - RS-9T Signature Series Slip-On (Honda)

 

NEW FOR 2017 HONDA CRF450R and CRF450RX!

Without a doubt the most anticipated Motocross and Off-Road bikes of 2017 have finally made their debut, the 2017 Honda CRF450R and CRF450RX have been released!

Introducing the all-new RS-9T exhaust system for the all new CRF450R and CRF450RX. The 2017 CRF450R's new engine and muffler configuration gave us the opportunity to create an entirely new system built specifically for the new CRF450 machines.

Yoshimura has been working tirelessly on development with American Honda HRC's engineers to achieve maximum performance and mass centralization, and to optimize rider usability. Yoshimura achieved all this while moving the rear muffler's all new RS-9T dual tapered shape forward to tuck in under the side number plates. Working with HRC race engineers and the all-new 449cc Unicam engine and its unique downdraft fuel injection system, Yoshimura engineers were able to deliver an exhaust that provides more trackable power and improved torque.

This new RS-9T dual works with or without Honda's all-new optional electric start system, and will be available as a slip-on set and a full system.

Some of the features on the new RS-9T dual CRF450R/RX system include:

Dyno and track tested by Honda R&D in Japan, American Honda MX team, and HRC All Japan MX Racing team

3 stage header provides overall broader range of power and better throttle response.

New tail pipe divider creates smoother exhaust flow and better velocity to the right and left tail pipe

New compact forward positioned RS-9T dual muffler design provides lower center of gravity for better mass centralization

New RS-9T mufflers have more volume than stock

Lager muffler volume provides decrease in dB level and better throttle response

Larger RS-9T core creates more power on mid and top end

Good fit
Color: Light Grey, Size: Medium
A nice vest and a true slim fit. Good quality for the price and no satin back, the material is used for the whole vest, allowing it to be worn without a jacket and still look smart. I am 6' 3" and 200lbs with a slim build, the Medium size fit like a glove, snug but not tight as a waistcoat should be.

Good Fit, Fold Lines
5'9, around 125-130 pounds, and the Small fit me just fine. Adjuster strap provides a great range of... adjustment. Good waistcoat if you are looking for something quick and cheap. With it being cheap, however, the material suffers. Due to it being folded while in shipping, there are seem lines going down the sides of the waistcoat which make it poke out and look awkward.

Great vest for a great price!
This vest is more slim fitting, stylish, & flattering than many vests. It fits as expected, but it is adjustable in the back, so you do have some wiggle room to tighten & loosen it if you’re unsure about the size. My son wore this vest to homecoming. He is 5’ 10” & 150 lbs, & the size small was a good fit.
