Kod Nama RN82 Dan RN83 Sahkan Yamaha Bakal Lancar R9 Tahun Ini?

Tahun 2021 merupakan tempoh sibuk buat Yamaha apabila melancarkan beberapa model baharu antaranya, MT-09, Tracer 9 dan Tracer 9 GT serta model serba baharu, YZF-R7.

Pengeluar motosikal Jepun itu turut memperkenalkan TMAX Tech Max 560 penghujung tahun lalu sebagai model 2022.

Bagaimanapun, perkembangan terbaru mendapati Yamaha tidak merancang untuk berhenti disitu apabila dokumen terbaru difailkan di Eropah mendedahkan terdapat dua model yang akan dilancarkan tahun ini.

Dokumen tersebut mendedahkan dua kod nama, RN82 serta RN83. Meskipun dokumen tersebut tidak mendedahkan apakah model yang dimaksudkan namun kod nama tersebut sudah cukup menjelaskan beberapa aspek.

Seperti pengeluar lain, Yamaha juga menggunakan kod nama yang dicipta bagi mengelaskan jenis motosikal tersebut.

Dalam kes ini huruf ‘R’ merujuk kepada model ‘street’ manakala model ‘cruiser’ akan mengguna huruf ‘V’ sementara motosikal ‘adventure’ akan guna huruf ‘D’.

Seterusnya, huruf kedua, ‘N’ pula memaklumkan bahawa motosikal tersebut akan dikuasakan enjin berkapasiti antara 750cc hingga 1,000ccc.

Jika huruf kedua adalah ‘M’ maka enjin tersebut duduk antara 600cc hingga 750cc manakala huruf ‘P’ pula merujuk kepada kapasiti lebih 1,000cc.

Maka, RN merujuk kepada motosikal jenis ‘street’ dengan kapasiti enjin antara 750cc hingga 1,000cc.

Jika melihat kepada kumpulan enjin dinyatakan, buat masa ini Yamaha cuma ada dua pilihan, enjin 889cc CP3 dari MT-09, Tracer 9 serta XSR900 dan enjin 998cc CP4 crossplane dari MT-10 dan YZF-R1.

Bagaimanapun, enjin CP3 lebih relevan kerana sebelum in terdapat dakwaan kuat bahawa Yamaha cadang perkenalkan MT-09 versi ‘full-fairing’, keputusan sama yang diambil sewaktu pembangunan YZF-R7 yang bernadikan enjin CP2 dari MT-07.

Apatah lagi Yamaha juga telah pun memfailkan tanda nama YZF-R9 di Eropah sebelum ini sekaligus menguatkan lagi dakwaan tersebut.

Kemudian, model seterusnya dijangka merujuk kepada generasi kedua Niken kerana motosikal itu merupakan model terakhir yang masih lagi menggunakan enjin 847cc CP3 Yamaha.

Naik taraf kepada enjin 889cc CP3 terbaru merupakan langkah rasional apatah lagi enjin terbaru itu mencapai standard Euro 5.

Apatah lagi kebenaran menjual motosikal bukan Euro 5 di Eropah akan berakhir pada 31 Disember tahun ini maka logik buat Yamaha untuk menaik taraf model tersebut.

Turn it Up! A Yamaha YZF-R1 and Aprilia RSV4 RF in the Twisties

Like beauty is subjective, so is everyone’s preference for motorcycle exhaust note.
V-Four engines are among the best – if not the best – sounding.
Listen to this Yamaha YZF-R1 and Aprilia RSV4 RF.

Just as beauty is subjective, so is everyone’s preference for motorcycle exhaust note. To bikers, the exhaust note is another aspect which stirs the sould. However, V-Fours sound the best in our books as demonstrated by this Yamaha YZF-R1 and Aprilia RSV4 RF.

Yes, yes, the Yamaha R1 isn’t a V-Four but an inline-Four, instead. But I’m sure you already know that the “crossplane” crankshaft is arranged in such a way that the engine fires like a V-Four, hence sounding like one. Or like some say, sounds like Valentino Rossi’s YZR-M1 MotoGP bike.

The crossplane crankshaft spaces the crankpins at 90^ofrom each other. Therefore, the R1’s firing order mimics the firing order of a V-Four with a 180^ocrank, which gives it a 270^o– 180^o– 90^o– 180^oignition timing. The irregular firing order is what gives the bike its distinctive exhaust note compared to traditional inline-Fours.

The Aprilia RSV4, on the other hand, uses a 65^oV-Four with a 180^ocrankshaft. As such, the firing order is a regular 180^o– 115^o– 180^o– 245^o, giving it another distinctive and gloriously LOUD(!) exhaust note.

By the way, the numbers with degrees denote the crankshaft rotation angle.

EICMA 2015: Yamaha MT-10 debuts

Having already set a milestone with its all-new 2015 YZF-R1, Japanese powerhouse Yamaha have opted surprise everyone by debuting the superbike’s naked offshoot during EICMA 2015.

Meet the all-new Yamaha MT-10 super-naked. Essentially, this is the budget-friendly Yamaha R1S superbike as we know it reborn as a streetfighter.

As far as its design goes, the work is rather controversial to say the least with Yamaha fans being divided over it. Nevertheless, we can’t argue at the fact that it looks rather sharp and quite futuristic, more akin to some of Yamaha’s radical concepts instead of a full-blown production bike.

More importantly, the MT-10’s arrival signals Yamaha entry into the competitive super-naked segment, and sees the brand completing its range of offerings to cover a wide spectrum of buyers. Yamaha has been absent in the high performance naked bike segment since perhaps the Fazer 1000 model.

Being based on the venerable R1 superbike, the MT-10 shares the same 998cc CP4 crossplane in-line four-cylinder from its fully-faired sibling, albeit detuned ‘slightly’ with just 165hp and roughly 101.6Nm of torque. Complementing the powertrain are features such as a three-level traction control feature, a slipper clutch, as well as a cruise control function.

The chassis is also derived from the R1S, with the MT-10 also retaining the same suspension set and swingarm assembly. And, minus the Bosch IMU, much of the R1S’s electronics package is also retained here in the MT-10. Other notable highlights include a full LCD dash, 320mm twin floating front discs with quad-piston radial calipers combined with a single 220mm rear disc with a sliding calipers, as well as ABS.

Clearly, Yamaha has got the BMW S1000R naked in its target crosshairs, explaining the standard equipped cruise control. This being based on the budget R1S, we can also expect this MT-10 to carry a lower pricing from the flagship R1 as well. There is no doubt though that the MT-10 now sits at the top of the brand’s MT naked model range.
