The BMW K 1600 GT and K 1600 GTL

             February 14, 2011 - BMW announced pricing today for the new K 1600 GT and K 1600 GTL. The K 1600 GT will have a base Manufacturers Suggested Retail Price (MSRP) of $20,900. The K 1600 GTL will have a base MSRP of $23,200. An additional destination charge of $495 is not included in MSRP.Both new models will be available for purchase through authorized BMW Motorrad USA dealers this Spring.

Riding dynamics, long-distance suitability and comfort.
For decades, 6-cylinder in-line engines have exercised a special fascination.  In addition to their perfect running smoothness they also offer supreme output and torque, giving the rider powerful emotional impressions.
Safety, equipment and comfort along with prestige and dynamic performance are the key criteria for a supreme touring bike.  With the most compact in-line 6-cylinder engine in serial motorcycle production to date, the K 1600 GT and the K 1600 GTL penetrate a whole new dimension in terms of riding properties, long-distance suitability and comfort.  They combine maximum agility and riding dynamics with a luxurious overall package.
With an engine output of 118 kW (160 bhp) and a maximum torque of 175 Newton meters, the 6-cylinder engine provides superb propulsion in all conditions.


Riding dynamics, long-distance suitability and comfort.
Previously, the in-line arrangement of six cylinders resulted in either very long or very wide constructions, depending on the installation position, which led to drawbacks in terms of chassis geometry, weight distribution and centre of gravity.  This where the K 1600 GT and K 1600 GTL break new ground.
Weighing 102.6 kilograms, the engine is by far the lightest serially produced 6-cylinder in-line engine for motorcycles in the class greater than 1000 cc.  What is more, the engine is significantly narrower in construction width than all other 6-cylinder in-line motorcycles in serial production to date.
This extremely compact construction and reduced width was achieved in particular by means of a cylinder bore of 72 millimeters in conjunction with a spacing of just 5 millimeters between the cylinder the cylinder sleeves.
Both the low engine weight and the consistent lightweight construction of the vehicle as a whole contribute to the low weight of the vehicle. At 319 kg (K 1600 GT without panniers) and 348 kg (K 1600 GTL with panniers and topcase) the new touring bikes are in the lower range of the segment.


Three modes to choose from and DTC (Dynamic Traction Control) for maximum safety when accelerating.
The rider of the K 1600 models has three different engine characteristics directly available at the press of a button at the right-hand end of the handlebars so as to be able to adapt to different uses such as touring on the road, riding on wet surfaces and sporty, dynamic motorcycling - the modes "Rain", "Road" and "Dynamic".  Available as an option ex works, the traction control function DTC is combined individually with the different modes, fully harmonised with them so as to provide maximum riding safety.
E-gas Throttle Control
The control of the central throttle valve with a diameter of 52 millimeters is effected via an e-gas, also known as a ride-by-wire system.  The rider's wishes are registered by means of a sensor in the accelerator twist grip. The engine control then adjusts the position of the throttle valve accordingly.
Chassis with ideal mass concentration for dynamic riding properties.
The essential chassis elements of the BMW K 1600 GT and K 1600 GTL are the light alloy bridge-type frame, and the Duolever and Paralever for wheel control at front and rear.  Because of the special requirements of a touring bike with a 6-cylinder engine, particular attention was paid to balancing the masses.
All in all, the interplay of chassis and engine position, together with the seating position of the rider, not only makes for a low overall centre of gravity with a very favorable concentration of masses, it also provides an ideally balanced wheel load distribution for excellent riding properties.  The combination of ride stability, riding dynamics and lightness of handling in all riding and load conditions sets a new benchmark in the touring bike segment.
Electronic Suspension Adjustment ESA II for optimum adaptation to all uses and load states.
The new 6-cylinder touring bikes also benefit from the innovative Electronic Suspension Adjustment II (ESA II), which is offered as a special equipment feature ex works.
With this system, globally unique on the motorcycle market, the rider can conveniently press a button to electronically adapt not only the rebound damping properties of the front and rear spring strut but also the spring rest ("spring preload") of the rear spring strut as well as the latter's spring rate and therefore the "hardness" of the suspension.  This makes for outstanding stability and impressive responsiveness in all load states.
The additional adaptation of the spring rate allows the damping settings "Sport, Normal, Comfort" to be spread widely in ESA II, giving them clearly perceptible characteristics during riding.  So in "Sport" mode, the K 1600 GT and K 1600 GTL are even more dynamic and precise and in "Comfort" mode they are more comfortable - while still retaining excellent stability.




Integrated operating concept with Multi-Controller, TFT colour screen and menu guidance.
The instrument panel of the K 1600 models comprises two classic circular instruments for the speedometer and tachometer and a 5.7-inch TFT color display.  The design of the information display is also completely new in the motorcycle field.  Among other things, it enables the attractive presentation of text and graphics over several lines.
Another world first is the Multi-Controller as part of an integrated operating concept, first introduced in the BMW R 1200 RT at the end of 2009.  In addition to audio system control, the K 1600 models also have a menu for operating the comfort functions and on-board computer

Cara Merancang Motor Balap Hemat Biaya Kemampuan Jempolan

          Untuk meningkatkan daya atau power mesin motor standart yang biasa disebut tune up, perlu diusahakan perubahan-perubahan pada beberapa hal :


  1. Meningkatkan / menaikkan      perbandingan kompresi.
  2. Memperbaiki porting IN maupun EX supaya pemasukan bahan bakar menjadi lancar dan baik.
  3. Merubah durasi, Lift noken as.
  4. Mengubah pengapian (apabila dalam perlombaan diperbolehkan).
  5. Mengubah rasio dengan Close Rasio.
  6. Setting karburator.


KOMPRESI
Meningkatkan perbandingan kompresi (Compretion Ratio = CR) adalah cara awal yang ditempuh oleh para mekanik untuk meningkatkan power mesin.
Namun demikian untuk meningkatkan perbandingan kompresi perlu diperhatikan beberapa faktor, antara lain bahan bakar yang digunakan dan kwalitas piston yang digunakan.
CARA MENAIKKAN KOMPRESI :
1. Mengganti piston dengan model racing.
2. Mendekatkan deck clearance.
3. Membubut Head.
4. Mengelas Head.
5. Membubut Blok dan Piston.
CARA MENURUNKAN KOMPRESI :
1. Merimer dome pada head.
2. Memperdalam coakan klep pada piston.
3. Membubut piston.

KEUNTUNGAN MENGGUNAKAN KOMPRESI TINGGI :
1. Power mesin meningkat.
2. Final gear menjadi berat.
3. Power mesin terasa dari putaran bawah sampai atas.
KERUGIAN MENGGUNAKAN KOMPRESI TINGGI :
1. Mesin menjadi cepat panas .
2. Engine break menjadi besar dan kasar.
3. Apabila perhitungan kompresi tidak tepat, sering terjadi detonasi





             Untuk mengetahui / menghitung perbandingan kompresi (CR) dari satu mesin, kita perlu mengetahui dulu volume silinder yang akan dikerjakan.
CONTOH PADA MESIN JUPITER Z O/S 100 Bore atau D : 52 mm = 5,2 Cm Stroke 54 mm = 5,4 Cm
= 0,785 x 5,22 X 5,42
= 114,62 cc ; 115 cc
CONTOH PADA JUPITER Z O/S 100
Volume ruang bakar diukur dengan buret lewat busi adalah 14,55 c
Jadi Volume ruang bakar 14,55 cc - 0,7 cc = 13,85 ( 0,7 cc adalah Volume Ruang Busi )

Cara menentukan berapa cc isi ruang bakar yang harus kita pakai pada perbandingan kompresi yang sudah kita tentukan.
Misalnya kita menginginkan perbandingan kompresi 1 : 14 berapa volume ruang bakarnya ?
Berarti apabila kita menginginkan perbandingan kompresi 1 : 14, isi ruang bakar harus 8,84cc. PORTING
Maksud dari mengubah porting adalah usaha untuk meningkatkan atau memperbaiki efisiensi volumetric dengan mengoptimalkan aliran gas ke dalam ruang bakar.
Ada 3 faktor yang menentukan besarnya tenaga pada sebuah mesin :
1. Efisiensi mesin yaitu seberapa dorongan pada piston yang dihasilkan oleh gaya putaran fly wheel.
2. Efisiensi thermal (panas) yaitu seberapa banyak bahan bakar yang harus dibakar/ dipanaskan dalam silinder untuk mendorong piston turun menuju TMB secara efisien.
3. Efisiensi volumetric yaitu membuat saluran / ukuran yang tepat untuk memompa gas secara optimal.
Dalam modifikasi, Head usahakan agar tidak mendapat hambatan apapun, misalnya lubang intake dengan lubang manifold atas juga harus sama dengan joint / karet manifold, usahakan dalam merimer supaya tidak ada ruang yang menyudut.
Di antara komponen pada motor yang paling utama untuk meningkatkan kecepatan mesin adalah memodifikasi camshaft / cam/ noken as. Noken as berfungsi mengatur buka / tutup klep yang dibutuhkan untuk mengatur bahan bakar melewati klep in dan membuang melewati klep ex secara selaras.


CARA KERJA NOKEN AS SEBAGAI BERIKUT :
1. Apabila titik A menyentuh pelatuk, maka katup mulai terangkat dan akan terbuka penuh setelah mencapai puncak tonjolan ( titik B ).
2. Setelah melewati puncak, katup akan turun kembali dan tertutup rapat setelah titik C.
3. Dari A kemudian naik ke C dan kemudian kembali ke B disebut durasi noken as.
4. Tinggi tonjolan menentukan Lift Max.
5. Bentuk permukaan profil tonjolan menentukan percepatan penutupan dan pembukaan katup oleh bentuk permukaan profil tonjolannya.
LIFT MAX
Cara menentukan Lift Max pada motor balap :
Secara teori untuk motor standart, Lift Max adalah 23% dari diameter klep in. Kemudian untuk motor balap dengan sirkuit yang tidak begitu panjang, Lift Max sekitar 29% - 31% dari diameter klep in. Untuk balap dengan sirkuit panjang, Lift Max dapat dibikin sampai dengan 35% dari diameter klep.
DURASI
Cara menghitung durasi ada beberapa cara :
1. Durasi dihitung setelah klep mengangkat 1,27mm pada setelan klep 0 (zerro).
2. Durasi dihitung pada saat klep mulai membuka pada setelan klep 0,10 mm.
Untuk mempermudah pembuatan, kita akan menggunakan cara yang ke dua.
Sebelum kita ingin menentukan angka durasi, harus kita ketahui dulu berapa LC (lobe center) pada noken as yang akan kita modifikasi.
Untuk mengetahui LC, kita harus memasang noken as pada mesin dan mengukur dengan busur derajat yang dipasang pada kruk as sebelah kiri /magnet.
Sebagai contoh : LC PADA JUPITER Z : 103
Kita menginginkan durasi 310 derajat. Berapa derajat in open dan berapa derajat in close ?
Perhitungan Untuk Mencari in close :
310 - 180 - 52 = 78
BERARTI UNTUK LC 103 JIKA KITA MENGINGINKAN DURASI 301 ANGKA DURASINYA ADALAH : IN OPEN 52 SEBELUM TMA IN CLOSE 78 SETELAH TMB
Untuk motor balap durasi idealnya adalah 29 - 33.
Untuk lift max motor balap durasi idealnya adalah :
7,5 mm - 8,3 mm
Keuntungan menggunakan lift tinggi dan durasi besar : - Tenaga mesin menjadi sangat besar - Mesin sangat bagus di putaran atas
Kerugian menggunakan lift tinggi dan durasi besar : - Pada putaran bawah kurang bagus - Per klep menjadi tidak awet - Klep floating / melayang apabila pir klep tidak kuat - Coakan klep pada piston harus dalam
CARA MENGGERINDA CAM
- Bagian Base Circle digerinda kurang lebih 18 sampai ketemu lift yang diinginkan
- Kemudian diikuti dengan menggerinda bagian ram untuk menentukan durasi
- Menggerinda bagian flank untuk menentukan lift O/L dan membentuk profil
- Usahakan dalam menggerinda sebuah kem dengan rata dan halus untuk menjaga agar rocker arm tetap awet dan mengurangi floating.
IGNITION / PENGAPIAN
Bagian pada mesin berfungsi untuk membakar campuran bahan bakar dan udara yang di kompresi oleh piston, sebelum piston mencapai TMA.
Sumber arus listrik untuk menghasilkan loncatan api bisa berasal dari spul atau langsung aki.
Sumber listrik yang dihasilkan langsung dari sepul sering disebut pengapian AC, dan langsung dari aki sering disebut pengapian DC.
Pengapian AC
Keuntungan menggunakan sistem AC :
- Sistem listrik langsung sesuai dengan putaran mesin.
- Tidak perlu menggunakan aki
Kerugian menggunakan sistem AC :
- Putaran mesin sedikit berkurang, karena gaya magnet yang ada
Pengapian DC
Keuntungan menggunakan sistem DC / Total Lost :
- Tidak perlu menggunakan magnet
- Berat rotor bisa dibuat sesuai keinginan kita (bisa sangat ringan)
Kerugian menggunakan sistem DC / Total Lost :
- Harus sering mengisi ulang (recharging) aki (accu)
- Resiko terjadi aki tekor
Perbedaan waktu pengapian standart dan yang sering digunakan untuk balap: Pengapian untuk motor standart • Pada RPM rendah (1.000 – 3.000
RPM) : loncatan api pada 8 - 15 sebelum TMA • Pada RPM tengah tinggi
(4.000 ke atas) :loncatan api pada 25 - 30 sebelum TMA
• Api busi tidak besar dibanding pengapian balap
Pengapian untuk motor balap
• Pada RPM rendah (1.000 – 3.000 RPM) : loncatan api pada 20 - 30
sebelum TMA
• Pada RPM tengah sampai tinggi ( 4.000 ke atas) : loncatan api pada 35
- 42 sebelum TMA
• Api busi besar
Macam macam jenis CDI
1. single map
cdi yang terdiri hanya dengan 1 map/kurve
contoh : cdi bawaan motor, cdi brt dual band
2. multi map
cdi yang terdiri lebih dari 1map / kurve yang dapat kita pilih sendiri dengan beberapa click.
contoh : cdi rextor adjustable, cdi brt smart click
3. cdi programable
cdi yang bisa diatur kurve/ grafik pengapian menurut keinginan kita, yang disesuaikan dengan karakter mesin yang dibutuhkan.
contoh : rextor programable, cdi vortec, cdi brt remmote.
