    In short, no. (theres was one made in the 80s but they were shit). It's the general character of the t5 gearbox. There is an easy solution tho, which is swap the standard 20t clutch gear for a 21. As usual there is a trade off as you'll lose some acceleration but cruising should be slightly better.

    sip sell one made by F.A italia but it's over 400 quid

    problem with the 5 speed boxes are the cogs are a quarter of their original thickness and are weaker - i still wanna try one though Razz

    On a normal flat road my t5 will get to 70 but which get there in time, not as quickly as other gears mind.

    Although, if there was a 5th gear in there? Do you reckon that it would carry on pulling well? I personally don't. As soon as mine reaches the power band at about 55 then I get to 70 in no time but still..

    its catch 22 cos you'd need a tuned motor to pull the taller gearing - but the extra power would just kill it with it being thinner and weaker

    i think if there was a 5th gear it wouldnt carry on pulling but it means you could sit at 65ish without ragging it

    till you get the sniff of a head wind or an incline

    i dunno it depends how spaced out the gearing is, it tells you on the sip site but i dunno what standard gearing is to compare it with

    You guys need to learn more about primary gear ratios...

    For a 5th gear to work, youd have a lower 4th gear so that the transition is minimal bewteen 3rd, 4th and 5th so you can easily saty in the power band.

    but with the kit you cant choose which ratio's are right for the scooters set up so its probably gonna be no good

    You will loose the acceleration in but it shouldn't scream quite as much in 4th. Tho as I said it all comes down to the characteristics of a T5 - they were designed to be peaky.

    as shaggs said i used to know a boss website to help knowing how to mix the teeth and how to make it either more acceleration more top end more torque and all that
