Renthal Motorcycle Sprockets

 

Renthal was formed in 1969 by motorcycle enthusiasts Andrew Renshaw and Henry Rosenthal
to make handlebars for trials bikes. The name is a combination - REN from Renshaw and the THAL from Rosenthal.

In 1975 Renthal sprockets entered the motocross market with full time production in Manchester, Northern England,
the very same place where the company resides today. The company had steady growth through the 70's and 80's
and finally broke into the US market in the early 90s. Renthal currently employs over 60 production staff
and Renthal sprockets are sold in 42 countries worldwide.

In October 2000, Renthal's factory was destroyed by a massive fire. What replaced the original factory was a completely new,
state of the art manufacturing and design facility. Renthal's 41,000 sq. ft. factory now uses the most state of the art equipment
available for manufacturing, quality control, R&D, and storage. This includes five Yamazaki two and three axis CNC turning centers,
seven Kitamura machining centers, one Kardex Shuttle 500NT automated vertical storage system, and a number of other custom specification machines. These custom spec machines include bar bending machines, a fatigue tester and drop test rig
created to fatigue aluminum handlebars.

In 2004, Renthal sprockets added to its list of records, becoming the first aluminium handlebar to be fitted as OE
on a Japanese off-road motorcycle, possibly one of the highest accolades of quality a company in this industry could receive.
 

    

Renthal Sprockets have been at the pinnacle of motocross racing for 35 years and with 153 World Titles
and 132 US championships are regarded as the leading handlebar and chain wheel manufacturer in the world.

Renthal sprockets are designed, developed and manufactured at our facilities in Stockport, England.
A purchaser of Renthal sprockets can therefore be assured that it has been manufactured by a company
run by engineers with an obsession for engineering excellence and quality.
This has been recognized by Honda, Kawasaki, Suzuki and KTM with the fitment of Renthal handlebars
as original equipment to their motocross models.

The same passion and expertise has been used to create our new range of road bike sprockets.
Our goal is to use the highest quality materials, engineering and craftsmanship to provide you parts
that are extremely lightweight and durable.

"A fraction of a second, a few grams, a couple of millimeters.   It all counts."
 

Renthal 520, 525, 530 Sprockets - starting @ $39.95

 


Front Sprockets
Renthal front sprockets are Case hardened and core refined 655M13 Nickel Chrome Molybdenum steel
and precision CNC machined to extremely tight tolerances for maximum longevity.
Certain models are available in a computer aided Ultralight™ design to minimize weight
and allow maximum power transfer to the rear wheels.


Rear Sprockets

Hard anodised for increase longevity.
Renthal Ultralight™ road and road race chainwheels are manufactured from specially enhanced high strength 7075T6 Aluminium alloy to give a good combination of strength and weight reduction. The chainwheels are CNC machined which ensures a perfect fit and concentricity.

Hard Anodising is an integral surface coating which significantly increases the hardness and wear resistance of the chainwheel surface, which results in increased wear resisitance.


SPROCKET Features
• Computer aided Ultralite™ design enables the ultimate combination of strength and lightness
• 655M13 Nickel Chrome Molybdenum Steel provides excellent longevity
• Precision CNC machined to extremely tight tolerances.
