there all the same these thumpster's all come from the same factory in china pretty much save ya money and get a big bike you will have fun on the thumpster but you will soon want more power and you feel every bump on them but it is your decision

true not really wat im after but thx for opinion

Thats looks to be one of the better ones like I had. what size engine? yx160 50?

With these suckers though its inevitable that after every ride or two you will need to check over virtually every bolt on the bike to make sure it hasnt vibrated loose.

They are plenty of fun to start off with but when you find your skill level improves these bikes will leave you wanting more and then you know its times to buy a bigger bike. Either a lot of fun and easy to learn on!

thx man cheers yea im jst leanring aye will be my first bike
are they decent bike and its 140 cc yx engine

I just recently sod my thumpster, its was a 140 but a lifan motor. Although it cracked the 90kmh pretty effortlessly and could mono 1st 2nd and 3rd gear pretty easily although it was quite modded for a thumpster but i'm sure you'll have plenty of fun if your just learning.

Just make sure your wear the right safety gear and keep your bike well serviced. This means changing oil every 2nd ride and cleaning air filter regularly. Also use a uni filter and get an inner rotor kit. Probably the cheapest and best mods to get the best out of your thumper. engine wise.

Parts are cheap so if you stack dont worry however with the amount of stuff and trick up parts you can buy for these things they still get expensive and leave you thinking why didnt i just buy a big bike haha

oh true true
yea ive got few mods in mind like bigger carby shit like that they say they can punch 100km

Yeah changing your gearing around will help you do that easier. Best carby you could use for that engine is a mikuni vm24 flatslide.

Other then that and an inner rotor kit the best engine upgrade would be a yx160

true true
i can get these nitrous in 140 cc 150cc and `160cc

Spend the extra and get the 150 minimum... atm they have more modding options like kits upto 188cc... or just get the 160 as you will quickly find the limits of the 140

true true thx for ya help man heaps im only newbie to motor riding dnt want ot buy a shit bike

check out www.miniriders.com.au

thx man had a look not a bad site cheers never thought they were out there the minibike forums

Buy a full size 125, or XR250 for the same 1000 bucks this thing will cost. The suspension, as stated will clap out faster than a bloke getting gonnorea in Thailand. Brakes are usually pretty shit too.

You can mono them in 1,2,3rd gears as it involves leaning back and popping the clutch.

Do yourslef a favour, save the dollars and blow your mates from here to freaking next Tuesday and buy a full size 125.

im not after full on full size bike jst after something to have fun on on weekends and im buying 140 or 160

try spelling it thum'P'ster as well when your searching for them....

first point thumpstars arnt that great for a long term bike but they are awsome to smash around on also i rkn u shud get a yamoto rather than a atomik as they fall apart rly easyly i found yamoto are built rly gud for a chinese bike... Yamoto renamed moto revo is on moss street

p.s. atomiks break within 10 mins

thx for the help guys cheers
