    14/15 bhp में इतनी जान ही नहीं होती sprocketing करके उसकी top speed बढ़ाई जा सके।
    Original condition में ही यदि wind resistance ज़्यादा होता है या road में थोड़ा सा भी inclination अधिक होता है या pillion rider भी होता है तो top speed कम हो जाती है और
    vice-versa situation में थोड़ी बढ़ जाती है
    इसलिये
    Rear Sprocket बड़ा करके या front sprocket छोटा करके acceleration/torque बढ़ाया जा सकता है लेकिन sprocketing करके कम bhp की Motorcycle में Top Speed बढ़ाई "नहीं" जा सकती।
    बेहतर होगा कि top speed बढ़ाने के नुस्खे बताते समय engine की loading क्षमता बढ़ाना भी बतायें।
    जय हिन्द !

    You are well accepted for using simple language for all to understand.
    Once explained in technical/mech terms try to get back to simple wordings.
    Leave a one or 2sec pause each time a term is explained.
    Background music is loud in this video and diverting.

    Highway mein chalna hai chote engine wali bike se to gear ratio ghatana jayaz hai
    City ke liye to company tune kar k deti hai
    Aur haan city mein chalane pe gear ratio ghatane se clutch jaldi ghisega lekin mileage acha ho jayega
    Pickup k saath compromise kar sakte ho to bohot achi cheez hai
    Mene bhi karvaya hai meri ride city mein 60 percent aur 40 percent city highway wali road pe hoti hai gaadi 60-70 ki speed 4000rpm mein pahucha deti hai

    • @vinirao5243
      @vinirao5243 3 ปีที่แล้ว

      Quite simple..
      It's up on the rider's skills and practice/experience! When u see commute riders or i say day to day rider( common man ), they pull the clutch, make a gap then change the gear again slight gap and then leave it slowly.. which is slower way to change and quite smooth if u do it right or else it affects the clutch plate badly, on the other side when u see a drag racer/ track racer, hey change gears way to fast ( in a blink of eye ) and that doesn't feel stressful to engine that's because they have known the timing of top speed at a gear and over revving at same and they make a quick movement to change gear which also won't make any stress to engine or clutch plate as it doesn't get rubbed over....
      ( this is a simple explanation for normal people.. people having no work to do please do not criticize and waste both of ours' time😁 )

    मैने मेरे TVS victor glx 125 cc मे front sprocket बदल दिया, अब हायवे पर मुझे कोई परेशानी नही होती.
    बहुत पेहले, front sprocket 13T का था और rear sprocket 43T का था लेकिन फिर मैने front sprocket 14T का डाला(हिरो स्प्लेंडर वाला front sprocket) और पिछे का sprocket वैसे ही रख दिया.
    pickup थोडा कम हुआ है लेकिन फिर 70 के स्पीड पर हायवे पर मुझे कोई vibrations नही आते(पेहले 13T का front sprocket था तो 50 के स्पीड के आगे ही vibrations आते थे लेकिन अब front sprocket बदलने के बाद मे हायवे पर ये गाडी चलाना अछा लगता है).

    Pulsar 200 NS carries14 teeth front and 39 rear while 200 RS carries 14 teeth and 43 rear…
    well depends on your daily basis.. whether you ride in traffic or on the highway, let's have a look.
    14/39- torque is inversely proportional to top speed which means this will deliver less torque during initial acceleration but increases its top speed. good for highway and long run
    14/43-in this case torque is again inversely proportional, which means more initial power but as a result, your top speed decreases. excellent to cut through the traffic.
