“STEER CLEAR.”

ONE OF THE WORST 'bikes' ive EVER owned. its a heap of junk, the electrics are prone to going wrong the carb gets clogged way too easily and its an all round Piece of Crud. DO NOT BUY. its also liquid cooled which is even worse the battery dies too easily and the kick start is prone to slipping.

“Best scooter on market! ”

Written on: 13/08/2012 by Brad1996 (1 review written)

I brought my suzuki ay50 for £340 and it's never let me down once ( apart from faulty spark plug costs £3 to fix ) it looks great and is very fun to ride. My mates have scooters and not one is nearly as fast off the mark, it can beat cars off the line at traffic light etc. the only problem I have ever had is when it's cold it would take a while on the starter motor to start ( 30+ seconds ) but I found out the auto choke was not connected proberly and now starts fine every time. I highly… Read Full Review

“great bike easy to use and very reliable ”

Written on: 07/06/2012

i got this bike for E250 , when i got it it needed a new battery and indicators, also the body was damaged bad enough. but once i fixed up those things and i gave i a new custom paint job ,it was ruining nicely. it does about 65km/h max speed on a straight road with barley any wind. but here is a good tip. you sould all ways store your motor bike / scooter inside a shed or if you dont have one use a rain cover because if you dont you will have to change the seals on the gasket every few mounts… Read Full Review

Sounds like the restricter is still on your bike! You need to see a Suzuki dealer to see if it's has been removed at the CID unit!

Written on: 09/06/2013

The katana has low gearing so will only get about 50 at max anyway, if your still getting 35 you need to upjet your carb 10% if you have a sports exhaust like a gianelli like mine, the only other restrictor is in the air box ive been told and you can buy and sports filter for around 15 quid which youll then need to upjet again to around a 96ish to match the air, also lighter rollers may make a difference in the acceleration speed

if it has a standard exhaust then that will have the restrictor in it as i have this bike and i have got a aftermarket straight through race pipe on it and it does around 45 - 50 mph i have been told to take the restrictor out of the air filter but as the bike is on high revs as it is and is screaming the knackers off of it and top end so i would just recommend getting a new exhaust..

“Really good bike”

Written on: 14/07/2011 by bigandfat (1 review written)

I brought my suzuki ay50 cheap and it has a viper exhaust system on it and not too sure if its got any other modifictaions but it has good acceleration and good top speed (48mph on flat road) for a 50cc moped that is really good. i would recomend you buy one as they are cheap and good fun to ride :) the only bad thing is the plastics are hard to get hold of new but thats the same for all mopeds. people have put really bad reviews about them but they are a quality bike for starting on and for a… Read Full Review
