The Harley-Davidson Twin Cam motors tend to be motorcycle engines created by Harley-Davidson since 1998. Although these motors differed dramatically through the advancement system, which often was derived from the group of single camshaft, overhead-valve engines that have been first introduced in 1936, they share several attributes with nearly all earlier Harley-Davidson engines. Both machines has two cylinders in a V-twin setup at 45, are air-cooled (some touring designs use liquid cooling for the heads), and turn on valves with push-rods. The crankshafts need one pin with a knife and hand arrangement when it comes to connecting rods. They are sandwiched between a couple of flywheels.

The Twin Cam 88 was launched the 1999 model seasons in September 1998. The Twin Cam 96 premiered when it comes to 2007 model year.

The Twin Cam initially had not been found in the Softail model families prior to the seasons 2000. This was as a result of the framework build and vibration transfer towards the Softail framework as a result of the direct (tough) mounting associated with the motor. Dyna models are “rubber mounted”, damping most vibration transfer into frame and driver. Another reasons is that system and transmission on a Twin Cam are directly bolted (but are however separate devices) to one another, aided by the chassis seat post on a Softail getting back in the way in which of a Twin Cam transmission situation. Because the company determined that a rubber-mounted Softail would impact the range’s aesthetic styling, Harley fixed the issue by designing an engine variant generally Twin Cam 88B. It is essentially the exact same engine while the initial (now labeled as “Twin Cam 88A”), but with a modified engine block build that integrate double chain-driven balance shafts. The Twin Cam 96B motor was released as well as Twin Cam 96A model, the 2007 design 12 months, and was prepared on all Softail versions until it was replaced because of the 103 ci version.

You are able, but to install a frequent Twin Cam motor to a pre-2000 Softail (or any chassis that allows an advancement engine), through third-party adapters.
Distinctions from forerunner (advancement motor)
The engine build differed quite a bit from its predecessor the “Evo” even though it shared some design elements aided by the Sportster line. The 88 presents the displacement in cubic inches of standard motor. The bore is 95.3 mm (3.75 in) together with swing try 101.6 mm (4.00 in), meaning the displacement try 88 cu in (1,450 cc). The Twin Cam 96 displaces 96.7 cu in (1,584 cc). The business introduced 103 cu in (1,690 cc) in 2010 Electra Glide super restricted models, and later for 2012 Softail versions and 110 cu in (1,801 cc) for Screamin’ Eagle/CVO brands.

Growth of the Twin Cam started in the first 1990s, as Harley needed to address problems influencing the last advancement system, especially structural weaknesses in the crankcase, oil blood circulation and leakages. While aftermarket firms such as for example S&S pattern formerly answered with stronger crankcase components for high-performance Evolutions, Harley moved for a totally latest build, while keeping the engine basically and aesthetically similar to the old-fashioned 45-degree, air-cooled overhead valve V-twin.

The Twin Cam best provided 18 section having its forerunner, as the majority of the components were unique toward engine. Because the name indicates, the engine utilizes two chain-driven cameras, to comply with EPA sound regulations. The drivetrain was reinforced through an installing plan called the “Revised Rear Interface”, permitting the transmission situation is mounted straight to the rear for the engine, because of the primary drive and clutch protects playing less of a structural role; this was also partially the reason for Softails maybe not in the beginning getting a Twin Cam the 1999 design season.

Early prototype Twin Cam engines had significant problems with all the oiling system. These issues delayed release of the engine as scheduled for the 1997 design 12 months. When the motors are run, oil arrived on the scene any gasketed joint as well as the breather. Harley tried the aid of Paul Troxler, a new engineer from Southwest Studies Institute and eventually the issue was traced to a design which exhausted the cam instance in to the crankcase, and made use of one scavenge pump. As a result of airflow through ports within the crankcase wall surface, the cam circumstances was not draining properly. After much examination, the clear answer would be to seal the cam circumstances through the crankcase and make use of a dual scavenge system, that was incorporated in to the engine, in the place of as an outboard pump as utilized on elderly Big Twins considering that the initial Knucklehead. However, oils had been nevertheless perhaps not scavenging precisely from the crankcase, and this was traced to an acoustic phenomenon as a result of caliber for the scavenge inlet. Restricting the diameter regarding the inlet, a counter-intuitive answer, resolved that problem.

Harley-Davidson has established an all-new 1584cc motor for many their 2007 Softail, Dyna, and Touring design larger twin motorbikes. Harley defines the latest engine as “the greatest new-engine program in history of Harley-Davidson.” The 96-cubic-inch powerplant possess over 700 newer parts. Really the only uncharged areas are top-end equipment: cylinders, rocker arms, rocker bins, and some related areas. Both variations regarding the system the counterbalanced Twin Cam 96B variation for Softail versions and also the non-counterbalanced Twin Cam 96 variation that rubber-mounts into the Touring and Dyna show spouse on Cruise Drive six-speed transmission introduced for 2006 into the Dyna household. All 2007 Harley gigantic Twin brands were fuel-injected. The TC96 keeps the look, design and layout of previous Twin Cam engines, with air-cooling, a 45-degree V position, and pushrod device operation.

Additionally, Harley-Davidson announced a few new or reconfigured 2007 products rest with changes that extend beyond the latest energy train.

A limited-edition 1200cc design celebrates half a century of Sportsters, of initially manufactured in 1957 once the K-series with 883cc machines. The 50th Anniversary Sportster gets a traditional peanut gasoline container, special badges, and extra touches to mark the 50th anniversary of this motorcycling icon. Suggested pricing is $9795, and manufacturing is bound to 2000 motorbikes.

The 2007 Sportsters join the remaining portion of the line by integrating Harley’s ESPFI gas injections as standard gear, a move without doubt needed by impeding emissions guidelines. However, fuel shot furthermore brings most immediate benefits. The four Sportster XL 883 systems has about 15 percent most torque at 2500 rpm because of the changes created using the new induction. To accommodate this new program, that will doubtless deliver improved driveability along with cleaner fatigue gases, Harley-Davidson redesigned the Sportsters’ rear fenders, chairs, supply tanks, coils, stators, exhaust pipelines, wiring and induction program, and modified the framework. Oxygen suggestions functions separately for each cylinder, so that the program “learns” and adjusts to changing conditions to produce optimal performance. In addition new this year were latest gauges with a clock contained in odometer Liquid Crystal Display, a low-fuel warning light as well as 2 tripmeters. It gets an eight % lowering of clutch lever work and an 11 to 14 percent reduction in front braking system lever energy, depending on design. Two-inch lengthening of handlebar wiring render bar swaps effortless.

For Softail aficionados, the reborn FXSTC Softail Custom brings right back a familiar name and small else from past. It offers a classic chopper-like style including a Chrome Profile Laced Aluminum 21-inch front-wheel and tire, a meaty 200mm rear tire on a slotted disc rear wheel, a unique king-and-queen saddle, stainless ape-hanger handlebar, a little bullet-style chrome headlight, a traditional Bobtail backside fender and a Fat Bob gas container adorned with triple-laid personalized decals and embossed fabric tank strap. There are several chrome and 10 colors options, which just take MSRP from $16,895 for black to $17,700 the three-tone color options.

The tremendously popular Softail Fat child enjoys not just the newest system and six rates, but gets updated with newer variations of the conventional gold, bullet-hole disk Cast Aluminum wheels installing a large 200mm rear tire in back with a 17-incher up front. Harley defines the restyled back fender as “extra sliced. His Fatness maintains that standard style thereupon oversized chrome headlight in front of a broad chrome front hand nacelle and giant bare knuckle risers and an extensive, fat personalized internally-wired handlebar. For 2007, the Fat Boy gets a fresh two-tone dual seat, plus the conventional Fat Bob fuel container wears a laced triple round step-by-step tank band and new customized visuals matching those regarding fenders. You’ll select 11 solid and three two-tone custom colors options, which enhance the price from $17,095 for black to $17,900.

The V-Rod families is welcoming two brand new brands in line with the 1130cc VR motor. The VRSCDX Night pole specific, which Harley’s launch calls “the evil twin brother associated with evening pole,” is very easily recognized with a wicked style put by an almost completely blacked-out finish. Their dark part are evident just about everywhere, including the 120-horsepower engine, the hyrdoformed framework, back once again fork sliders, black colored triple clamps, swingarm, color-matched black screen visor, brushed Straight-shot Dual fatigue with black end caps, black colored fatigue shields, black Machined Slotted disk throw aluminum rims with orange pin-striping and a black on (you guessed it!) black paint system. The chair has been restyled slightly. Recommended price is $16,495.

Another latest V-Rod, the limited-edition VRSCX, pays homage to your scorchingly successful Screamin’ Eagle/Vance & Hines NHRA professional Stock bike dragracing team with more than simply radical drag-race styling and elements. Additionally it is armed with a 1250cc, 123-horsepower version of the VR double-overhead camshaft system. Race-inspired touches feature drag taverns, ahead base settings, a Profile Laced Aluminum front-wheel with a cast back wheel installing equivalent 240mm tire because the Night pole specialized, drag visor and paint and artwork featuring a redesigned type of the Harley’s custom #1 logo. Only 1,400 products will undoubtedly be created at a suggested cost of $19.995, and wheelie taverns aren’t standard equipment.

The ability improvement provided by the new 1584cc engine might be more welcomed by customers of Harley’s Touring series motorcycles, since they may load their particular machines adequate to fully employ the extra torque and horse power. Undoubtedly including the six-speed Cruise Drive transmission may also be appreciated most by cyclists of Electra Glides in addition to other countries in the Touring familiy because the brand-new proportion set lowers rpm by about 11 percentage in full gear on the highway. Our experiences with this particular drive train furthermore pledge much light clutch pulls and far smoother, most controllable clutch wedding, properties you don’t completely value until such time you need ridden the bicycle in visitors or turned around in a tight spot.

Within the Dyna family, the FXDC Dyna Super Glide Custom is massaged with a brand new two-up, ribbed seat, a Fat Bob gas container with a broad Glide-style tank-mounted speedometer and ignition console, additional chrome and other custom details, including a mini-pullback handlebar. It starts at $14,645 in black colored and $14,970 in Ebony Pearl, Ebony Cherry Pearl, Deep Cobalt Pearl, Pewter Pearl (a fresh color), or Yellow Pearl. You can add the newest security system on the latest brands for $325, and placing the recommended Profile Aluminum Laced rims on your Dyna Super Glide Custom instead of the cast wheels will create $450.
