GT250 vs Ninja 250 vs CBR250 Torque and HP Comparison.

As expected, inline buat lebih kuasa kuda, Ninja 250 24.9hp vs GT250 24hp. CBR250, single cylinder buat the least hp, just 22.6hp. Yang menarik, In real speed, GT250 dan CBR250 akan tinggalkan ninja up until 7500RPM, masa ni GT250 akan mula tinggalkan CBR250, somewhere along the line of 9000RPM, Ninja 250 akan mula pickup speed dan bila gT250 dah peaked dekat 10 000 RPM, Ninja 250 akan slow slow mai, using it's extra 1hp. tapi let's get real, untuk real cruising speed, CBR250 dan GT250 will do just fine dekat 7-8K RPM, while Ninja needs to be 9K above to be as efficient as these two.

Torque figure dia yang interesting. Macam stated in old skool books, bila sebut pasal torque, the less cylinder the better, dan V is always superior than any inline. Delivery wise, CBR250, sebagai single, conquer mid-range, dan buat peak torque dia in the mid ranges dengan 15.1 lb-ft, GT250 comes second, tapi still dengan character V-Twin, GT250 pun buat peak torque dalam mid range, all 14.8lb-ft of it. Ninja 250, typical inline character, tak ada oomph dekat both low and mid range, not untill 9000rpm, dan peak torque dia is just 13.3lb-ft.

Yang menariknya, bandwidth torque ke tiga tiga motor ni. GT250 dah mula buat lebih dari 12 lb-ft torque dari 3000rpm sampai ke redline, since torque ialah kayu pengukur real world performance, GT250 ada torque curve yang lagi flat dan usable dari serendah 3000RPM sampai ke redline (flat torque jugak akan buat motor rasa tak ada pick up since tak ada stepping)

CBR250, walaupun raja torque dari 3 motor ni, tapi torque dia stays sub 12 lb-ft until 4700rpm. In a static roll off, gt250 akan tinggalkan CBR250 1-2 meters dan real competition will only start between 5K ke 7K RPM antara GT250 dan CBR250, tapi seriously, kalau naik awana or layan corner2 bukit, 5-7k rpm ni is where you will be, next time naik awana intai la RPM meter kalau tak cayer hehehe. CBR250 will fair well dekat corner-corner bukit, since 5-7K RPM ni is just natural bila dekat kawasan2 macam tu. But in super tight sub 5000rpm turn (macam dekat kuil tu) GT250 have an edge.. a whole extra 3lb-ft of torque. Senang cerita, kalau chase down a CBR250, kena tunggu corner kuil tu to untuk fight exit at low RPM. Unless rider CBR250 boleh gantung rpm at 5K (or Ninja at 9K rpm) at almost 180 degree turn, chances are, GT250 akan exit dulu dan buat gap dekat situ.

Ninja 250 pulak, in the other hands, got no advantage over torque against dua dua motor ni. nature inline, revvy, bermakna, Ninja 250 perlu rely banyak pada gearbox dia untuk get the most of its 13.3, kalau nak main short corner bukit, rider Ninja kena keep above 9k untuk best performance dan never drop below 6k rpm, no lazy corners for the ninja.

In other words, being a typical V, engine malas, GT250 tak ada hp figure setinggi Ninja, or torque setinggi CBR, tapi GT250 ada advantage in both.

Dia kalah HP dengan ninja by 0.9, tapi dia menang by 1 pound of torque by 9000RPM earlier.
Dia kalah torque dengan CBR250, tapi dia menang torque curve by 3000RPM earlier dan menang by 2hp over the CBR once dapat jalan kosong to rev over 7.5K RPM.

Kalau lepaskan serentak naik awana lalu karak dari Tol melati, Ninja leads dekat karak, CBR entah ke mana, GT250 tangkap balik Ninja dekat uphill route (since ninja dengan gt250 top speed lebih kurang je 160kmh) masa ni CBR makin mendekat, using all its extra torque, dekat corner temple tu, GT250 lead, dan sampai atas kat starbuck tu, in order, GT250, Ninja 250, CBR250...

Tapi tu make all this real, GT250 kena tayar lagi best, dan suspension belakang up-rated. BTW, berat Ninja 250 dan GT250 sama, CBR wins in weight department by 10-15kg lighter.

Masa turun pulak, most probably CBR yang turun dulu since dia ada ABS dan dia lagi ringan. Ninja 250 struggle untuk guna high rpm torque n hp dia kat downhill while gt250 struggle dengan mono lembut dan brake kayu dia, miahahahahaha, tapi kalau rider ninja dengan cbr pakat minum kopi cepat2 sebab sampai dulu, kena lak cbr.. apapun, in the end kalau test Gombak - Genting - Gombak, Ninja akan sampai Gombak dulu.. just because of the extra hp, better suspension dan brake, dan jalan karak yang luas. Unless GT250 tu dah uprate suspension dan braking, fighting chance tipis walaupun dia boleh order kopi dulu kat Genting.
