Kawasaki KLX 200?
Jika benar ini memang sangat realistis mengingat KLX 250 maupu D-Tracker 250 harganya selangit di atas 30 juta. Ini seperti langkah Honda yang katanya akan mengeluarkan motor 150 cc bermesin CBR 15 R dan rangka tubular yang mengambil segmen harga di antara Mega Pro dan Tiger. Harapan biker akan dituruti di KLX 200 ini. Dengan mesin sedikit lebih besar, ada kemungkinan motor ini pakai ring 18" di roda belakang dan 21" di depan. Dengan begitu jarak tanah ke jok pun meningkat. Entah akan diambilkan dari mesin motor apa ini KLX 200. Mengingat di Kawasaki pusat sana adanya 140 cc (dipakai KLX 150 S) dan di atasnya ada 250 cc. Mungkin ini benarr-benar varian baru hanya saja brother semua tak akan mengetahuinya dari website manapun karena bisa jadi Indonesia sekali lagi ditunjuk sebagai yang pertama untuk perilisnya seperti Ninja 250 kemarin.
Pantas ditunggu.

30 hp for Ninja 250

Standard power of Ninja 250 is 36 hp on 11.000 rpm. But the real power on the rear gear is reduced to 23,59 hp on 10.600 rpm, refers to Tomy Huang from Bintang Racing Team (BRT)’s test with dynotest. For a while, BRT produces four upgrading components for Ninja. They are CDI, jet kits, muffler, and ported valve and cylinder heads.
BRT’s i-DTIS is programmable until 30 steps (30 ignition spots on the specific rpm) and operated with remote control. Moreover, this TIS have system called dualband which means there are two curve options for riding in the straight lane or for rolling speed in the corner. The way to managed is only push the ON/OFF button on the left handle bar.
After the i-DTIS was installed and other parts were still standard, as a result the maximum power could be achieved was 24,81 hp. The difference is until 1,48 hp.
The next test is the installation of racing muffler and i-DTIS which have tested before. For example, BRT used R9 New Mugello. “The character is noisy on the low rpm but quite silent and smooth on the high rpm.” said Suar, the mechanic of BRT.
Following the test with Dynojet, the power raised quite high. In the last test the power is 24,81 hp and after the muffler installation lifted until 28.58 hp. The price of this
Dynojet Kits priced for about Rp. 1 million contained of main-jet, 2 needle-jets, and 8 bits. The needle jets are used for medium rpm gasoline set. And the bit is meant for enlarge the wind hole.
From the test using AFR (Air Fuel Ratio) the right main-jet is number 94 and 40 for the pilot-jet (from Keihin FCR) which we prepare before because it is not available in the Kits. The raising power after installing these devices is 0,59 hp or become 29,17 hp.
The process of porting for BRT has two secret weapons. First of all, Tomy Huang toke his study in
The important porting in Ninja is on the valve stick. It should reduce or a half than the original size. The second one is the top end of the valve which shaped like an umbrella. For this part is made two corners 45 and 30 degrees with a tool called reface valve. The sitting valve is also rebuilt with sitting valve cutter. Thus, on the 11.700 rpm the power could be achieved is 30,43 hp.
