Harley-Davidsons are special. Aside from their unsocial "potato-potato" exhaust note, they guidelines isolated from astir motorcycles chiefly owed to their single-pin crankshaft creation and their belt last drives. Some person earned a estimation for being nan coolest motorcycles astir while besides being the astir difficult motorcycles to handle. Harley-Davidson utilized concatenation last drives each nan measurement up to nan 1980s, pinch nan loop last thrust first debuting connected the FXR Super Glide II. Considered arsenic low-maintenance and quieter alternatives to concatenation drives, loop drives soon became mainstream successful Harley-Davidson motorcycles, moreover connected newer Harleys for illustration the Nightster that feels truthful right, it must beryllium wrong.

That said, immoderate Harley riders still prefer chain drives. Those person been astir since nan inception of motorcycles and person mostly remained unchanged since then. That's because concatenation drives are durable and known to past for a agelong time. This leads to a batch of questions. Why does Harley-Davidson insist connected loop drives while immoderate Harley riders insist connected chains? And if you were to switch your Harley's loop thrust for a concatenation drive, what do you request to know? Before that, let's brushwood up connected nan types of drives and whether loop aliases concatenation is better.

You request a mean to get nan powerfulness from your motor to nan driven wheels for your conveyance to move. For four-wheelers, it is mostly done via a thrust shaft aliases propeller shaft. Two-wheelers  — motorcycles successful particular — mostly trust connected concatenation drives to get nan occupation done, but immoderate usage loop drives instead.

A concatenation thrust consists of a metallic concatenation that links a sprocket connected nan gearbox output shaft to a sprocket connected nan rear wheel. Belt drives run connected nan aforesaid principle, but alternatively of chains and sprockets, you person geared pulleys and a loop pinch teeth connected nan soul side. These teeth mesh pinch nan teeth connected nan pulleys, providing nan driving power. 

Harley-Davidson made nan move from concatenation to loop thrust arsenic nan second was smoother and quieter. Belt drives usage Kevlar aliases carbon-reinforced belts pinch precision-cut grooves, meshing perfectly pinch nan gears successful nan pulleys to connection a soft operation. They are besides comparatively low-maintenance and cleaner since they do not request greasy and messy lubrication, dissimilar concatenation drives. If decently maintained, a loop thrust tin past up to 100,000 miles. 

However, it is easy to harm a loop drive. If mini stones aliases rocks get successful betwixt nan loop and pulley, they tin easy harm nan former's teeth. They tin besides get ripped isolated nether daze loads, specified arsenic erstwhile you propulsion a wheelie aliases abruptly accelerate. While nan loop has bully tensile strength, a sizable daze load tin easy transcend its power.

Chain drives are each astir sheer strength. They tin grip sadistic daze loads without coming apart, which is 1 of nan reasons why they're truthful durable. They are besides much businesslike than loop drives, offering 1-4% transmission losses compared to a loop drive's 9-15%. Chain drives besides return up little abstraction than loop drives and connection a cheaper and wider action of altering last thrust ratios by changing nan sprocket sizes. These are besides much resistant to breakage owed to overseas objects being stuck betwixt nan concatenation and sprocket. However, while concatenation drives are incredibly strong, they do request regular cleaning and lubrication, arsenic good arsenic hostility checks. Also, an unfastened concatenation group will fling lube complete your rear instrumentality and trousers.

Some Harley riders switch their motorcycle's loop thrust pinch a concatenation for a fewer important reasons. For one, a concatenation thrust is much durable and little susceptible to damage, truthful it makes consciousness for personification who puts agelong miles connected their motorcycle successful less-than-ideal roadworthy conditions. Also, connected nan road, it is easier to hole a surgery concatenation than a belt, which cannot beryllium repaired. Those who support their ain bikes for illustration concatenation drives, arsenic replacing a loop requires extended disassembly, which sometimes includes dropping nan swingarm. Harley riders modifying their bikes for sports specified arsenic resistance aliases ungraded racing mightiness take to switch to nan more-durable concatenation drive. Custom motorcycle builders mightiness besides for illustration concatenation drives arsenic they connection a minimalistic, cleaner look compared to nan ample and ungainly-looking belt-and-pulley system.

As a Harley rider, should you do nan swap?

If you thrust a banal Harley-Davidson, time off your bike's attraction to nan professionals. If you for illustration your motorcycle spotless and your rides chiefly dwell of pristine highways, instrumentality to nan loop drive. These execute flawlessly successful nan situation they are intended for. A loop thrust offers a soft and quiet operation, is debased maintenance, and tin past agelong if looked aft properly.

However, if you person modified your Harley to nutrient precocious horsepower, it is simply a bully thought to move complete to a concatenation drive. Chances are, nan banal loop thrust can't grip nan further performance. Also, if you thrust aggressively, emotion to propulsion wheelies, aliases execute stunts connected your Harley, this is 1 modification you should look at. Another logic to move complete to a concatenation thrust is if you want to thrust much successful nan dirt. Harley's ain escapade bike, the Pan America 1250, uses a concatenation thrust and does everything you doubted it could off-road.

While switching complete to a concatenation drive, location are immoderate factors to consider. You request to acquisition nan correct conversion kit; it's not a straightforward fit, arsenic loop thrust Harleys are not designed for a concatenation thrust setup. Go pinch nan conversion kit for your circumstantial motorcycle exemplary and manufacturing year. You request to guarantee that your transmission and rear instrumentality sprockets are aligned straight; astir conversion kits see nan offset sprockets aliases spacers. You'll besides request to cheque for concatenation clearance, arsenic nan concatenation could swipe against nan rider footpeg mounts aliases muffler mounts. You mightiness moreover person to modify aliases region nan loop defender for a cleanable fit.
