    I have a new (to me) Speed Triple and it's great, I'm not sure if this a 'standard' experience of something I could smooth out but the initial application of power from idle is quite jerky and abrupt when at low revs - which makes for slow moving/filtering 'fun'

    Some context, is that I'm newly back to biking but I don't ever remember my old 748 and 996 being like this.....but that said it could just be me getting used to riding again

    Once past the initial low revs, it runs nice and smooth. The only thing not standard are the high level Arrow cans, there is a more than expected amount of slack in the beginning of the throttle movement that I will try and tighten up to see if it makes any difference but your views would also be appriciated

    Cheers

    Hi andyc1 - It's a 2011, not sure if it has been re-mapped at all

    I had a 2015, which was snatchy from idle. The demo I tried was the same, my mates 2014 was the same.
    So I guess a caricteristic of the bike

    Double check clutch freeplay in the cable, iirc should be about 5mm freeplay

    Chech chain tension, if it is too loose it could cause snatch pick up

    Due to Euro4 environmental legislation, there may be a dip in the fuel map around 3k to 4k revs, I know there is on my 2010 Speed Triple
    Keep revs just above that area and feather the clutch as you pull away/filter

    Had mine taken to be put on the dyno and remapped last year, made it much smoother with more punch in the midrange, upped it from 125 to 138 bhp too.

    My RS splutters around 3k rpm, feels like a lack in in fuel. I thought it maybe due to euro regs and your comment as confirmed that. I think I will get it remapped at some point
