Inside the engine there is a higher compression CP Piston and Hinson clutch components.

Yoshimura prides it’s self on its superb quality and the RS4 system doesn’t disappoint. It is constructed from high-grade titanium and terminates in a sleek tapered carbon fiber silencer.

The low-speed compression front and rear was made more responsive which would help absorb impacts at the initial phase of suspension stroke.

As the fork and shock compress deeper into its stroke the compression was slowed down to better control chassis pitch under medium-to-heavy loads.

The exhaust uses its duplex chamber which works more effectively with the mechanical pulses of the engine thereby increasing power output.

It’s actually really difficult to put in words how the clutch feels. But the biggest thing is that its feel and the point at which it engages/disengages is consistent whether you’re on the first lap of your moto or the last and that in turn helps elevate the rider’s confidence in his machine.

Yoshimura applied its Superfinishing Process (ISF) to the transmission gears to improve performance and shifting.

With the throttle wrapped to the stop, the engine piles on revs much faster than stock. It’s actually incredible how snappy engine response with it spinning up with a similar feeling to that of a brand-new 250F.

The potential for more speed means the need for added braking power. So Yosh fitted an oversized 270mm diameter Batfly rotor kit from Braking.

“It’s one of the smoothest bikes I’ve ever road,” states Chris “If you want to grab a gear and jump a triple right out of the corner this bike will to do it.

Yosh began by reworking the heart of the motorcycle, the rearward-slanted 449cc water-cooled Single. The first order of business was to port and polish the cylinder head to increase the “efficiency” of the engine.

Next to the reasonable price, with both the fork and shock being serviced and re-valved for only $375, the best thing about Noleen is that it covers its work with a 45-day warranty.

Our Yoshimura-prepped Yamaha YZ450F is one of easiest (and fastest) motocross bikes we’ve ever ridden.

Overall we like the way the suspension moved but we ran out of adjustment range with the fork and felt that it was slightly under sprung.

One of the biggest attributes of our modified YZ450F is how well it hooks up out of the corner.

with the addition of the Windham-bend ProTaper bar, the ergos become far more accommodating for a taller rider.
