JT are the leading manufacturer of aftermarket motorcycle sprockets, with the largest and most advanced factory in the world.

Motorcycle Sprockets made the right way...

There's only one way to make a sprocket that meets the highest quality standards and thats hobbing, machining and drilling. This gives the closest tolerances and most accurate tooth profiles.

...with the right materials...

By sourcing the best quality raw materials for their motorcycle sprockets, JT can ensure the best quality end product.

JT are the only manufacturer to use ultra-durable high carbon C49 steel for their motorcycle sprockets. This is a higher carbon steel than the typical C45 steel used by other manufacturers (including original equipment manufacturers) and so is harder and stronger than many other sprockets on the market.

...to meet or exceed the highest quality standards

Each JT sprocket goes through 10 individual quality control checks before leaving the factory to ensure that it meets or exceeds the highest quality standards for the motorcycle industry. And a good quality sprocket means less wear on the drive chain.

Rear Sprockets

• 42 Teeth - standard for CRF1000
• 45 Teeth - standard for RD07/RD07A
• 46 Teeth - standard for RD04
• 49 Teeth - standard for RD03

Increasing the number of teeth on the rear sprocket will increase acceleration but reduce your top speed.
Reducing the number of teeth on the rear sprocket will decrease acceleration but increase top speed.

Front Sprockets
16 Teeth - standard on RD03/04/07/07A

Increasing the number of teeth on the front sprocket will decrease acceleration but increase your top speed.
Reducing the number of teeth on the front sprocket will increase acceleration but decrease top speed.

We have taken the industry leading Chain Guide from Acerbis and combined it with our own anodised aluminium mounting bracket to offer a serious upgrade over the stock chain guide.

The Acerbis 2.0 Chain Guide Block easily replaces the entire O.E.M. unit and ensures durability and high resistance to shock and wear from the chain. 

Made of Nylon Polyamide PA6, the block is manufactured in two parts that allows installation without having to remove the chain.

• Bracket - anodised aluminium
• Chain Guide - 100% PA6 construction.
• Available in either BLACK, BLUE or RED
• Highly resistant to shock and chain wear.
• Made of two pieces, allowing it to be mounted without removing the chain.
• Supplied with all required fixings and spacers to mount to your CRF1000 Africa Twin

"...The sprocket your bike would choose..."

 

• A tough, durable, long lasting sprocket.
• Formed of the best quality Japanese-sourced materials.
• Made with the latest sprocket manufacturing technology.
• A longer lasting sprocket means a longer lasting chain.

Supersprox are probably the largest producer of aluminium motorcycle sprockets in Europe and America, but their passion is in the production of the Supersprox-stealth. A product they invented, developed and patented. This is a product that they can honestly say is the most technically advanced and insanely attractive sprocket in the world.

What is the Supersprox-stealth about? 
Supersprox-stealth is about longer life, without compromising weight. Primary goal, to last 3 times longer than aluminum and remain as light as possible. No concession, it's performance and function first and last.

Better than steel! 

Supersprox-stealth is infinitely better than steel! You just can’t achieve this level of strength on a steel sprocket with the same weight. Sure, there are light steel sprockets out there, but they can’t handle the torque. Pound (lb) for foot pound (ft/lbs), Supersprox-stealth is the best.

Better than aluminium sprockets! 

OK, this is no contest! Try 20,000 miles on a Hayabusa with an aluminium sprocket or the whole Dakar rally on one sprocket. What about the Baja 1000? These are extremes and factory teams actually buy Supersprox-stealth for these gruelling challenges. Don’t waste your money on aluminium, invest in Supersprox-stealth.

Will a steel sprocket damage my chain? 

Kind of stupid sounding question, but there’s a lot of misinformation out there. So, think about bearings for example. They`re steel on steel and that works pretty well. Steel on steel is the best combination. So when someone tells you different, you should ask if they only sell aluminium. We guarantee our sprockets. If they don’t do what we claim, you can have your money back.

Are the rivets strong enough? 

There is no doubt, riveting is the only possibility for fixing such a high performance sprocket. We know how to use this technology, forging rivets into the sprockets. We have never had one single rivet break since starting to produce these sprockets. That’s 1,260,000 rivets.

It’s for your bike! 

It’s perfect for any bike up to 1400 cc. Do you have a powerful 4 stroke or performance street bike? Covering high mileage or road racing, then this is your best option. A single sprocket can last more than 20,000 miles (with correct maintenance). Whatever your bike, if you want peace of mind and the knowledge that you have the best of the best, then choose Supersprox-stealth.

NEMO 2 was developed by the company COBRRA. It is a modern original device for chain lubrication that saves you money, and time relating to your chains maintenance, and provides you with the unique comfortable new feeling of a well oiled chain.

MAJOR FEATURES

NEMO 2 consists of three interconnected work chambers that provide the following:

• easy NEMO 2 application of oil
• continuous oil displacement under pressure, therefore uniform lubrication and maximum chain life
• lubrication of NEMO 2 internal parts in order to obtain a high reliability and longevity

NEMO 2 works on the principle of compressing the oil in the chamber and pressurising it through a valve and down the line onto the chain. Therefore it is not necessary to change the oil depending on the ambient temperature. It works reliably in warm and cold weather. The rider can apply the oil on to the chain when its required with a simple 1/4 turn of the Nemo 2 which will displace enough oil over a 3 minute period giving you up to 200 miles of lubrication after each 1/4 turn of the Nemo 2.

NEMO 2 is installed on the motorbike handlebars or frame and provides immediate chain lubrication whilst riding, for instance after:

• rides in the rain
• fast rides
• rides in a dusty environment
• certain mileage

ADDITIONAL NEMO 2 FEATURES

• Great return on investment on NEMO 2 compared to the cost of regular manual chain cleaning and lubrication
• Extraordinary time saving with regard to cleaning and lubrication compared to the manual art of chain maintenance
• Simple and fast installation without the need for electronics or vacuum feed to run the devise.
• Great quality & design made of light aluminium alloy and anodised
• simple, fast, and easy operation during riding, turn NEMO 2 in arrow direction by 90° and after 3 minutes application of oil the chain & sprockets are lubricated for up to 200 miles
• function of lubrication interruption in case of incidental stop during lubrication
• function of impurities wash out from the chain
• suitable for use in any conditions
• outstanding durability during the lifetime of the chain & sprockets resulting from the following:
  • immediate lubrication – of the chain & sprockets when you need it
  • uniform lubrication of the entire chain – the oil is continuously displaced under pressure
  • oil – the oil gets displaced to the intended location on the chain lubricating the 0-rings or x-rings
  • lubrication with ordinary 80W-90 transmission oil, adhesive oil for riding at high speed, BIO oil for riding wet roads, or any other suitable oil
• single NEMO 2 filling provides chain lubrication for up to app. 3 000 miles
• visual check of NEMO 2 filling level directly on the motorbike handlebars
• oil level alert – emergency oil reserve in NEMO 2 for app. further 300 miles
• simple and easily accessible oil filling directly from a large or small bottle
• reduction of chain power loss due to easy chain operation without stuttering
• low oil consumption – if the running motorbike is standing, the chain is not lubricated
• chain lubrication does not cause motorbike contamination by oil
• the hose is steadily directed towards the chain by means of hose rectifier made of light aluminium alloy
• oil distribution through inconspicuous thin black pressure hose

Function and operation principles of NEMO 2

• The lubrication procedure is performed during riding by twisting the NEMO 2 in the arrow direction by ¼ of revolution (recommended oil amount).
• The lubrication is accomplished after approximately 3 minutes of slow oil dissipation to the chain.
• The lubrication procedure shall be performed every 100 up to 200 miles depending on drive velocity, dustiness and meteorological conditions.  It is recommended to lubricate the chain after each refueling for the purpose of regularity.  After riding in rain and after cleansing the chain when the chain is free of lubricant completely, it is necessary to lubricate the chain (it is recommended to turn the NEMO 2 by ½ of revolution)
• When the lubrication procedure is performed and the motorcycle is to be stopped within 3 minutes incidentally, it is sufficient to slew the device against the arrow direction into the original position and the lubrication process is stopped.  After putting the motorcycle in motion, perform the lubrication procedure again.
• If the compartment of the NEMO 2 will not turn anymore it is empty and it will need to be refilled.
• Oil level of NEMO 2, fill to the top and fit the lid making sure the oil seal is in place.
• The stainless container may be used as ready-for-use oil.
• When following the recommended oil quantities, the chain will be lubricated optimally and the motorcycle chain will not have excess oil on it.
