  • @Astat4 Short pistons i believe

  • Why so many Rpms?

  • @jsmorel86 I guess so. But i'm not much of a bike guy so I wouldn't really know a whole lot about them. I guess it does make sense however especially since the cam is much lighter in a bike than in a vehicle.

  • @TheOneMetallica1 ive seen these bikes with over 100,000 kilometers on them. so i guess your wrong.........

  • All that friction thats being produced can't be good for the cam shaft

  • @Pavouk106 CBR250RR - 23NM

    ZZR250, Ninja 250R - 22NM

    RGV250 - 40NM

    KR1S - 36NM

  • @airsoftwarrior666 Not to worry when in the higher gears, but to rev it like that in neutral, I'd be worried just in case I destroyed the crankshaft, flattened the cam lobes or blew the piston rings. I reved my ZZR600 to about 7000rpm in neutral and that I didn't feel happy about.

  • @Blackrier93 What the fuck are you on about? That's the most stupidest comment I've ever seen and it made me laugh because it is so silly. If it had no compression, it would probably not start let alone rev so responsively. The CR on most of these machines are in the regions of 11:1 - 12:1. Mr Honda realised that investing in racing had several benefits and anything that revs in the regions of 18 000rpm is F1 territory. Involvement in racing does push technology forward.

  • @Blackrier93 Dont talk out your arse, these bikes usually have a 11.0-1 compression ratio, they rev high because of a very short stroke. They are not quite f1 standards, (f1 cars are not very reliable, so arent any good on the road anyways), but what Honda learnt in f1 they used to develop these motorcycles.

  • sound like vacuum cleaner
