JT Sprockets 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 Sprockets can ensure the best quality end product.

...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.

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.

The OEM Honda front sprocket has a rubber cushion which acts as a very basic cush drive, which we feel reduces wear on the output shaft more so than any aftermarket front sprocket.

We only fit these to our own fleet of Africa Twins.

Perfect for reaching the deep spark plugs on your Africa Twin.

Anyone who has tried to remove the spark plugs from their Africa Twin will know that unless you have an extremely thin-wall socket, nothing is going to get in there!"

This spark plug spanner is manufactured specifically for this purpose.

HEL brake lines are British manufactured and tested on the most demanding roads and tracks around the world.

Lifetime warranty
The highest quality components and build of a HEL brake hose means that HEL can offer a life time warranty with all brake hose kits.

Hel Braided Brake Hoses: Front Race Set Up
The race set up has a separate line from the master cylinder to each caliper. Many people find this system easier to bleed than an over-the-mudguard setup, as in an over-the-mudguard setup air bubbles can get caught in the arc of the shorter hose. (See comparison of setups below).
Race hoses are required for race days where over-the-mudguard setups are banned.

What's in a Hel Race Set Up Brake Line Kit?
• Stainless Steel Brake Lines
• Stainless Steel Banjo Bolts
• Copper Crush Washers
• Fitting Guide
• Personal Lifetime Warranty Number

Stainless Steel Braided Brake Hoses
All HEL hoses are made from stainless steel braided fluoro-polymer - this avoids any corrosion issues and prevents distortion of the hose thereby increasing the efficiency of braking compared to a rubber hose.
A PVC coating is applied during manufacture, not heat-shrunk on afterwards, which protects your bodywork, and importantly stops any grit getting into the stainless braid and potentially causing wear. Not all manufacturers coat their braided lines with PVC!
The swaged fittings are lighter and slimmer than reusable fittings and are all made of high quality stainless steel.
Each HEL Performance brake line kit is assembled in-house from the finest quality stainless steel fittings swaged directly to hard drawn tensile stainless steel braided hose.

Why HEL Brake Hose?
HEL Brake line kits eliminate that 'spongy' feeling often found with rubber hoses under extreme braking conditions - the time when performance is needed the most. By replacing the original rubber hoses with our complete system you will remove this sponginess and your braking will deliver new levels of precision.
Don't risk using inferior brake lines when you can trust us to improve braking reliability and performance - We use stainless steel in our lines and our fittings. Most competitors use zinc plated fittings which are at risk from corrosion.
• Smoother & Stronger Braking
• Finest Quality Stainless Steel Braided Hose
• Stainless Steel Fittings and Banjo Bolts
• Eliminate That Spongy Feeling
• Sharper and More Responsive Braking
• Lifetime Warranty
• More Reliable Braking System
• Superior Abrasion and Corrosion Resistance
• Race Proven Technology

Safety
HEL hoses are proven time and time again both in the lab and on the race track.
Manufactured in the UK, HEL pass all requirements of FMVSS-106; strict testing criteria that all hoses must pass to be legally used on the road. These standards are then used by:
• DOT and NHSTA (USA),
• TUV (Germany),
• ADR (Australia),
• LTSA (New Zealand),
• IDR (Israel),
• MOT (Europe).
Having passed these requirements with flying colours, HEL Performance brake lines can be used anywhere in the world.
HEL Performance are very proud of the fact that all the brake line components are made in Britain, including the stainless steel braided brake hose and all the stainless steel brake line fittings. From small beginnings HEL performance products have gone global and are now available all over the world in over sixty-eight countries and, having passed stringent safety standards by regulators across the globe, are street legal anywhere in the world.

One other salient point - HEL brake line kits come with a lifetime warranty - what's not to like!
