Info Seputar Ban

Jika Anda pemilik kendaraan, entah itu kendaraan roda dua, tiga, empat
ataupun lebih dari empat, info Roda tentu bemanfaat.
Sebab info seputar Si Karet Bundar yang lazim dikenal dengan nama Ban,
dikupas habis. Ada beberapa tips yang hadir mengenai cara untuk merawat Ban
agar
tetap nyaman dan juga tahan lama. Tips tersebut adalah :
1. Ukuran ban dan corak telapak ban harus sesuai. Minimal pada satu as memiliki merek serta
ciri khas yang sama.
2. Gunakanlah Ban dengan kontruksi yang sama (misal : dari bahan Polyester atau baja).
3. Ban Tubles harus dipasang pada pelek yang khusus untuk ban tubles. Begitu pula
sebaliknya. Karena jenis ban yang menggunakan ban dalam tetapi menggunakan pelek
tubeles, akan mengakibatkan berkurangnya tekanan angin. Sementara apabila Anda
memilih untuk menggunakan ban jenis tubles, jangan memaksa untuk menggunakan ban
dalam. Sebab pada kecepatan tinggi panas udara dalam ban akan cepat naik dan efeknya
Si karet bundar setiap saat mudah meledak.
4. Pemasangan ban dalam harus disesuaikan dengan jenisnya dengan ban luar. Dan apabila
memungkinkan gunakan ban dalam yang semerek dengan ban luar.
5. Perhatikan pula kondisi Ban yang Anda gunakan pada kendaraan Anda.
Caranya untuk dapat mengenali kondisi si Karet bundar begitu mudah. Kenali Si Karet
Bundar dengan melihat petunjuk TWI (Thread Wear Indocator). Jadikan angka ukuran
pada TWI sebagai patokan. Sesudahnya, coba Anda ukur dengan penggaris ketebalan
alur ban dari dasar alur. Jika kurang dari 2 mm sebaiknya Anda segera ganti ban
Anda dengan yang baru.
Tips diatas, tentunya bermanfaat bagi Anda. Namun tentu ada diantara Anda yang
kurang begitu memahami karakteristik ban yang di jual di pasaran. Amat mudah
untuk mengenali jenis ban yang Anda gunakan. Coba Anda perhatikan sisi ban. Pada setiap jenis
ban akan tertulis sejumlah angkat atau huruf yang sebenarnya telah menjelaskan secara mendetil
karakteristik ban. Misalnya, pada sebuah ban tertulis 195/65R15 92H.
Apa yang tertera di samping ban dapat dikategorikan sebagai berikut :
1. Angka 195 merupakan petunjuk lebar penampang ban. Semakin besar ukuran
penampang ban, semakin besar pula telapak ban.
2. Angka 65 R merupakan petunjuk mengenai ketinggian ban diukur mulai dari
pelek hingga penampang ban yang menempel pada jalan. Semakin besar
angkanya maka semakin tebal pula dinding ban jika dilihat dari samping luar
(jika diukur dari pelek).
3. Angka 92 H menunjukkan kecepatan minimum dan juga maksimum ban.
Semakin besar tingkatakn angka yang ditunjukan maka semakin besar pula
kekuatan ban terhadap kecepatan tertentu.
Untuk angka terakhir yang disebutkan ada sedikit penjelasannya. Dalam dunia Si Karet Bundar,
pihak produsen biasa mencantumkan kode standarisasi kecepatan ban. Ada beberapa klasifikasi
kecepatan yang dicantumkan pada setiap jenis ban, klasifikasi tersebut adalah :
1. TR Ban jenis ini mampu digunakan untuk kecepatan kendaraan sekitar 100 Km/jam.
2. HR Ban jenis ini mampu digunakan untuk kendaraan yang melaju dengan kecepatan 210
Km/jam.
3. VR Ban jenis ini dapat digunakan pada kendaraan yang mampu melaju pada kecepatan 260
km/jam

4. ZR kode tersebut menunjukkan bahwa ban jenis ini mampu digunakan pada kendaraan
yang mampu melaju pada keceparan 340 km/jam.

Mana kode ban yang kiranya sesuai dengan jenis kendaraan yang Anda miliki, silakan Anda sesuaikan. Hanya saja, Anda perhatikan pula perawatan ban yang Anda gunakan seperti apa yang dituliskan diatas. Sebab salah-salah ban yang Anda gunakan justru menjadi bumerang dan berakibat kurang baik.Sebagai infomasi tambahan, bagi Anda yang suka bepergian tak ada salahnya jika Si Karet Bundar diberi sedikit cairan penambal. Dengan cairan tersebut, maka dijamin Si Karet Bundar akan aman-aman saja. Sebab fungsi cairan penambal tersebut yakni merekatkan kembali bagian ban yang tertusuk benda tajam. Bahkan adad sejumlah bengkel mengatakan bahwa untuk jenis paku dengan panjang 10 mm yang menusuk pada ban dapat tertahan. Oh ya, jika Anda merasa takut cairan tersebut akan merusak bagian dalam ban, Anda tak perlu khawatir. Justru cairan tersebut melindungi bagian dalam ban sekaligus melindugi pelek Anda dari goresan. Cara membersihkannya pun terbilang mudah, Anda tinggal semprotkan air pada bagian dalam ban, ataupun mengelap bagian dalam pelek dengan lap kering. Mudah bukan ? Nah informasi yang dikupas habis mengenai dunia seputar Si Karet Bundar diatas kami harap dapat bermanfaat bagi Anda. Karena maklum, dalam  kondisi yang kurang menentu seperti sekarang tips dan trik berguna jenis apapun pastinya ingin Anda  dapatkan. Terutama bagaimana caranya untuk dapat mempetahankan keawetan ban.

Rossi on Ducati

Tuesday, 9 November 2010

Valentino rossi took to the Valencia track shortly after midday on Tuesday on day one of the Official MotoGP Test. See the first images in a free video here!

 

After a lengthy wait on Tuesday morning due to a wet track Valentino Rossi finally gave the masses of awaiting media at Valencia the moment they, and MotoGP fans, had been eagerly anticipating.
Just after 12.20pm local time the 31 year-old took to the Ricardo Tormo track on board the Ducati Desmosedici, with a new fairing – completely black – and donned in plain black leathers, with his trademark 46 emblazoned in luminous yellow on his back.
The main focus of the two-day Test for the Ducati Team is the decision on whether to go with the screamer or big bang engine on the GP11, as discussed by Filippo Preziosi in this interview.
Ducati Test rider Franco Battaini first warmed both versions of the bike up prior to Rossi’s exit from Pit Lane, after which the rider completed a first run of no more than eight laps to gain an initial feeling with the bike. Rossi then re-emerged just before 1.10pm as he began a second stint.

Lorenzo leads the way at Valencia Test on day one

Tuesday, 9 November 2010

The 2010 World Champion was quickest ahead of Casey Stoner (Honda) and new Yamaha team-mate Ben Spies. Valentino Rossi made his much-awaited Ducati debut, whilst British rookie Cal Crutchlow continued his adaptation to MotoGP.

Valencia Test 2010 - Day two - MotoGP - Highlights

Less than 48 hours after the conclusion of the 2010 season preparations for 2011 began with the first of two days of the Official MotoGP Test at Valencia on Tuesday.
Assuming top spot on the timesheet at the Ricardo Tormo circuit as he had done on the podium on Sunday was factory Yamaha rider and 2010 World Champion Jorge Lorenzo, who led the 17-strong field of riders with a best time of 1’32.012 from 48 laps on his M1 machine – a little over two-tenths of a second off Casey Stoner’s pole position time from the weekend.
“Today has been a great day, we tried a new chassis for 2011 and while it doesn’t seem better it’s not worse. The most improved thing has been the Öhlins suspension, which gave me more confidence especially mid-corner. The new engine seems to make the bike wheelie less too,” said Lorenzo.
“Tomorrow we will concentrate on confirming everything and understanding whether every new part is an improvement or not, and go over everything.”
Stoner was one of the enthusiastically awaited debutants of the Test as he rode the factory Repsol Honda machine for the first time, clocking in with the second fastest time of the day at +0.763s on Lorenzo’s time. He was just a tenth outside his own FP3 time from the weekend.
Stoner was comparing a new 2011 chassis against that of the 2010 one used by his new team-mate Dani Pedrosa as he completed 44 laps, and the Spaniard was just over a tenth of a second further back in fourth position as he worked on the same aspects as Stoner with HRC’s aim being the selection of a direction to take for their 2011 frame. Pedrosa, who completed 35 laps, had limited track time due to an electronic issue and is also still recovering from his broken collarbone.
Sandwiched between the Honda riders and in third position was Ben Spies who started work in earnest as a factory Yamaha rider. The American set an almost identical time to Stoner and completed a similar number of laps on his M1.
In fifth and sixth were another two Honda riders in San Carlo Honda Gresini man Marco Simoncelli, who was 0.007s behind Pedrosa, and factory rider Andrea Dovizioso as the pair assisted with the chassis work being undertaken by HRC, the former trying a new suspension.
Colin Edwards (Monster Yamaha Tech 3) and Rizla Suzuki rider Álvaro Bautista registered top-eight times, and were followed in the top ten by Ducati duo Nicky Hayden and Valentino Rossi.
The Italian’s debut on the Desmosedici GP11 caused great excitement and he was one of the first riders on track just after midday. By the close of play the 31 year-old had completed 56 laps as he set about tackling the task of helping his new team decide between a screamer and a big bang engine for 2011 whilst also riding with a new fairing on the machine.
Other riders debuting with new teams were Randy de Puniet with Pramac Racing and Hiroshi Aoyama with San Carlo Honda Gresini, whilst Cal Crutchlow continued his adaptation to the M1 of the Monster Yamaha Tech 3 team having gained a first taste in a private test in Japan at the end of October. The 25 year-old Brit had a non-consequential crash at turn six when on new tyres in the afternoon.
Back on a Ducati for the first time since 2007 was Loris Capirossi as he rode the Pramac machine used by Mika Kallio in 2010, putting in 71 laps, with Héctor Barberá making some slight adjustments to the Paginas Amarillas Aspar machine’s electronics. 2010 Moto2 World Champion Toni Elías (LCR Honda) and Valencia Moto2 race winner Karel Abraham (Cardion ab Motoracing - Ducati) also benefitted from solid lap totals.

Stoner Has Good Feel with Honda

Second fastest time on day one at the Valencia Test and 44 laps left the Australian extremely happy with how his first ride on the RC212V went.

 

Casey Stoner closed out the opening day of the Official MotoGP Test at Valencia in high spirits after a very satisfying first ride of the RC212V machine. The Australian, working with the Repsol Honda team for the first time, set the second fastest lap of the day as he immediately settled on the prototype.
“I had a very good day. I was disappointed that we couldn’t get a full session in this morning because of the weather, but it dried out and gave us some hours of good track time this afternoon,” said Stoner, whose lap time of 1’32.775 was 0.763s off that of Jorge Lorenzo’s.
“It’s been very exciting these past few days waiting to get on the bike, and then having to wait again this morning. It’s been a great experience to get back on a Honda, the way it feels is fantastic,” added the 25 year-old, who rode on an RC211V in his debut premier class season in 2006.
Stoner tested the 2011 chassis against the frame ridden by new team-mate Dani Pedrosa in the 2010 campaign, and gained a positive feeling from the bike as he clocked up 44 laps in total throughout the day.
“We’ve been working on a few different things but mainly just trying to get a bit of a better feel, and things like my seating position and brake levers. The day has been great. Tomorrow we have a few more things to work on and try,” explained Stoner.
“We’re trying to understand the electronics system and what sort of direction we want to go in, and at the same time trying to get comfortable with the bike. There’s no point giving a lot of data at the moment but at the same time we have to try and push on because there’s not a lot of test time before the start of the season. We need to get as much information as possible before the winter break.”
