Race Specification at an incredible price!
- In order to have as many people enjoy this kit as possible, a new machine has been invested in to reduce manufacturing time helping to reduce cost.
NOTE: Many HKS competitors use an OEM crank to reduce costs whilst increasing stroke. The HKS Crank has been designed and made to racing specifications using the most suitable materials and manufacture ring processes. Forged pistons, Forged conrods and a crank made from special forged materials allows this kit to be suitable to even 600PS

Circuit test proven & Made in Japan reliability!
- After plenty of testing on the engine dyno, the kit was tested in conjunction with the GT3240 kit to produce the 600PS CZ200S which went on to perform at various time attack events.

RHDJapan Store Reviews

Excellent customer's service! The CS team already set my expectations that item i ordered will be delayed, and still got it a month earlier. This is for the bride mask. thank you! 5 stars!

I’ve been anticipating this item for weeks and finally from the coasts of Japan to my American Doorsteps. While inspecting the beauty and quality of the part, I realized that this was not the item that I ordered. The item I wanted and ASSUMED I was purchasing, was the one that is shown as the display picture on both RHDJapan and Monster Sport Product Page. So I’m not entirely sure where the fault lies. I do know that I’m not willing to ship it back internationally, wait for a refund, purchase product again and then wait several more months just to receive the correct version. The difference is just minor styling.

Either way, back to the review, Item is clearly top notch quality, and as far as appearances go, Monster and Gruppe make the only Radiator Cooling Shrouds worth buying for the Evo X... the rest just looks bad.

I wanted to replace my rusty original hose just like I was replacing the brake hoses, and these one has the added benefit that there is no modification needed to attach it to either variances of slave cylinders; although not having a locating tab means that you would have to hold the line by yourself while torquing down the banjo or you will twist the line and destroy the washers, causing a leak, or even the line end.

The clutch pedal feel improves just like when you upgrade the brake hoses for the same kind of line.

You can find the correct picture for the product, with the brass block for the hard line, in APP's website.

Very easy and quick install, you will feel the improvement if you are sensible enough and care a lot about how your pedals feel.

I did paint mine flat black as the blue and red are too much for me.

We have much of dark night conditions and are in need of proper lights, PIAA and RHDJapan got us covered! Quality is premium as you would excpect
