Thank you for
visiting the "TWR PRODUCTS JP" page!
★"TWR-JP" has devised a "強化パーツ® = Reinforced parts" system that
prevents seizure caused by insufficient lubrication in the engine head peculiar
to RFVC engines, uneven wear of contact surfaces, galling and multi-hole
symptoms.
By increasing the
amount of oil discharged from the crankcase oil bolt that pumps engine oil from
the oil pump to the oil line and the oil bolt that introduces engine oil to the
cylinder head, high lubrication is quickly performed from start to full rotation.
"TWR-JP" establishes this
system and is a "強化パーツ® = Reinforced parts" for the purpose
of improving the metal wear resistance of the camshaft and rocker arm ASSY of
the RFVC engine and the cooling effect of the engine head.
◆Characteristics
of oil line "強化パーツ® = Reinforced Parts" bolt
1. “Full cone
orifice system”
By expanding the discharge port diameter of both the oil pump and the engine head oil bolt, and by uniquely revising the shape of the discharge port of the genuine parts, we have achieved +30% more engine oil flow.
2. “Double discharge
port system”
The oil bolt
discharge port on the oil pump side has been changed from single to double to
quickly maintain lubrication of the engine head mechanism from startup to high
rotation.
3. “smoothing system”
Reduced
lubrication loss by tapering the bottom of the oil bolt.
4. “High strength
and high durability”
One-piece
molding and cutting using high steel material specifications.
★Engine head
assembly has few opportunities for maintenance such as inspection and
disassembly, and is a part group that has always endured high rotation and high
temperatures. Considering the life of the component parts and the cost of
replacing parts, the "Oil line reinforced bolt" can be
easily replaced!

lubrication. <60,000km run with the genuine

●Photo 12~14: The
state of the RFVC engine camshaft and rocker arm after 36,000km driving with
the "reinforced bolts" installed. (The contact
surface between the camshaft lift and rocker arm is in very good condition with
no uneven wear or galling, and the lubrication effect of the "reinforced
bolt set" is fully demonstrated)
◆Regardless of seasonal
temperature changes, the rate of oil temperature rise due to heat generated by
the RFVC engine is much higher in city driving and short-distance high-speed
driving [STOP & GO] compared to
non-stop driving including touring. (This has already
been confirmed in Japan, which has four seasons)
This is because
the oil temperature is slow to drop, and the inside of the engine head, which
is far from the oil pump, gets hotter than expected, making it easier for the
oil film to break. It particularly affects the contact surfaces of rocker arms
and camshafts and tends to accelerate metal wear. [If you have an
oil temperature gauge, you can see the situation in real time...]
★Since its release in Japan
in 2010, it has been extremely popular as a standard customization for
strengthening the lubrication system among users and bike shops who own many
RFVC engine-equipped bikes. Furthermore, it has been selected as the best-selling engine lubricant parts ranking on online shopping sites.
◆All component parts are made in Japan. Manufacturers of parts used are listed in the product details.
★"Full cone
orifice, double discharge port, bottom taper" are
manufactured using "unique technology and
processing devised by TWR-JP" for each
vehicle model and displacement. In addition, it is safe and
secure as it has been registered with the Japanese Industrial Standards JAN/EAN common code. Furthermore, "TWR-JP" has obtained a
license from the Central Packaging Registration Bureau "ZSVR".
