采用滾子搖臂
sp滾子搖臂在猴型發動機的竹川超級機頭+r超級機頭上享有盛譽,在立式發動機上采用了滾子搖臂,以提取超級機頭的最大輸出性能,同時。滾輪搖臂的設計,可以提高中高速的動力輸出,並保持高轉速的動力輸出。<滾輪搖臂降低了凸輪軸與滑塊式搖臂之間的摩擦阻力(工廠零件型),搖臂內的滾輪軸承使凸輪外形從低轉到高轉都能平穩地跟隨。
通過用鋁材鍛造搖臂本體,克服了滾子軸承增加的重量。
鋼制氣門彈簧固定器
m8火花塞
由於采用大口徑氣門,使氣門口直徑增大,氣門塞孔與氣門口之間的壁厚減小,所以采用 "m8火花塞 "以保證足夠的壁厚。這樣可以防止氣缸蓋因熱變形而損壞,從而保證輸出穩定。
空心凸輪軸帶噴油嘴
凸輪軸中心有一條油管,將油引到凸輪鏈輪上。凸輪鏈輪中心產生的離心力將油液從凸輪鏈內部分布出去,從而提高了凸輪鏈的耐久性和潤滑效果。同時,由於機油噴射通過凸輪軸凸輪表面,可以從凸輪表面噴出機油,達到有效冷卻和潤滑的目的。
凸輪軸兩端由滾珠軸承支撐,以減小油軸頸的摩擦阻力(廠件型)。
另外,由於采用了`油道,凸輪軸體的重量大大減輕。
凸輪軸有三種不同的外形(SR-25/SR-30/SR-35),可根據應用情況進行更換。
帶油路的凸輪軸支架
凸輪軸支架采用了全新的油路結構,與缸蓋內的油路相連接,讓機油在每個細節上都能得到潤滑。另外,還設置了用於將油引導到帶油嘴的空心凸輪軸的通道,以支持凸輪軸和凸輪鏈的潤滑。<氣缸標配有出油口。另外,還可以安裝棒狀溫度傳感器來測量氣缸的溫度。

活塞
鉬塗層活塞裙,可更好地與發動機初始接觸。
長沖程曲軸
高性能曲軸的設計,使曲軸重量與沖程容積達到最佳平衡。使用高精度曲軸軸承可以減少振動,提高曲軸的動態性能。同時,飛輪軸還進行了特殊的表面處理,以提高抗疲勞性和抗磨擦性。
■Super head +R
Inherited from the "Super Head (Stage 3) " which enables high output with large diameter valves and smooth intake and exhaust ports, the "Super Head (Stage 3) " is equipped with proven roller rocker arms and a new oil line structure for even higher output and durability. It is a high performance cylinder head.
Port Diameter
Intake: 29mm / Exhaust: D-type port
Valve Diameter
Intake: 28.5mm / Exhaust: 23.5mm
Valve stem shaft: 4.5mm for both intake and exhaust
Valve Springs: Double spring with inner spring and outer spring
Roller rocker arm adopted
The roller rocker arm of SP Takegawa's Super Head +R for Monkey engine is adopted for the vertical engine to maximize the output performance of Super Head and to maintain the output at mid to high speed range and at high rpm range which is the feature of roller rocker arm.
The roller rocker arm reduces the frictional resistance with the camshaft that occurs with the slipper type rocker arm (stock part type), and the roller bearing in the rocker arm follows the cam profile smoothly from low to high RPM.
The rocker arm body is made of forged aluminum to overcome the weight increase by using roller bearings.
Steel Valve Spring Retainer
M8 spark plug adopted
Since the wall pressure between the plug hole and the port is reduced due to the larger port diameter caused by the adoption of a large-diameter valve, an M8 spark plug is adopted to ensure sufficient wall pressure.This prevents the cylinder head from being damaged by thermal deformation, thus ensuring stable power output.
Hollow camshaft with oil jet
An oil line is installed in the center of the camshaft to guide the oil to the cam sprocket.As a result, oil is sprayed from the center of the cam sprocket by centrifugal force from the inside of the cam chain, increasing the durability and lubricating effect of the cam chain.In addition, an oil jet passage is provided on the camshaft cam surface, so that oil can be sprayed from the cam surface and cooling and lubrication can be performed effectively.
The camshaft body is supported by ball bearings on both ends to reduce the frictional resistance that occurs in the oil journal (stock parts type).
In addition, the weight of the camshaft body has been greatly reduced by the adoption of an oil passage.
There are 3 types of camshafts with different profiles, SR-25 / SR-30 / SR-35, and they can be replaced according to the application.
Camshaft holder with oil lines
By installing a new oil line structure in the camshaft holder, the oil line is connected to the oil line in the cylinder head to enable detailed oil lubrication.In addition, a passage for directing oil to the hollow camshaft with oil jet is provided to support lubrication of the camshaft and cam chain.
■Cylinder / Piston
Ceramic Mexi Linder
This is an all-aluminum ceramic mesh cylinder with excellent durability, airtightness and heat dissipation.
The cylinder is equipped with an oil outlet as standard.In addition, a stick temperature sensor can be installed to measure the temperature of the cylinder.

Piston
The piston skirt is coated with molybdenum for better initial adhesion.
■Long stroke crankshaft
High performance crankshaft designed for optimum crankshaft weight balance against stroke volume.The crankshaft and bearings are manufactured to a high degree of precision to achieve low vibration and greatly enhance the motion performance of the crankshaft.Special surface treatment is applied to the shaft of the flywheel section to improve fatigue strength and galling resistance.
