burns1989 Posted October 17, 2014 Report Share Posted October 17, 2014 Hi how do you tell the difference of a 125 and 250 rev 3 as it does not state any where to say what cc it is . And my bike seems not to have the same pull that my techno had and seems abit tame Quote Link to comment Share on other sites More sharing options...
dadof2 Posted October 17, 2014 Report Share Posted October 17, 2014 CC is usually cast into barrel. Note the engine number and ask Beta-uk.com. I have not tried recently but you used to be able to look up your engine / frame number on their website. Quote Link to comment Share on other sites More sharing options...
burns1989 Posted October 17, 2014 Author Report Share Posted October 17, 2014 Yha i know but it doesn't say the cc any where just looked at the Web site and it doesn't show anything to check fram and engine numbers . Just got righting but nothing to state cc . Seems stupid to not have anything to say what it it Quote Link to comment Share on other sites More sharing options...
zerorev3rev4 Posted October 17, 2014 Report Share Posted October 17, 2014 what year is it , i think 06 on they had chrome forks as did the 200 as a pose to black , i think the older techno do feel more responsive than the equivalent rev3 but check if its got a flywheel weight ,, maybe ring lampkins with frame number Quote Link to comment Share on other sites More sharing options...
burns1989 Posted October 17, 2014 Author Report Share Posted October 17, 2014 It's a 2006 with black forks Was off eBay iv herd the 10th number is the year of the bike but not sure if it's true as it would make it's a 2005 . Quote Link to comment Share on other sites More sharing options...
dadof2 Posted October 17, 2014 Report Share Posted October 17, 2014 Take the exhaust off and turn the engine until piston is at bottom dead centre. Measure the vertical distance from the top edge of the piston to the cylinder head joint, I think it will be about 6.8 cm. Measure the diameter of the piston. Suppose the diameter of the piston is 6.5 cm then 6.5 / 2 =3.25 3.25 x 3.25 = 10.56 capacity in cm3 is 10.56 x 3.14 x 6.8 = 225 cm3 the 3.14 is Pi, just use this number Quote Link to comment Share on other sites More sharing options...
bilks Posted October 17, 2014 Report Share Posted October 17, 2014 (edited) Look at the Exhaust as in this picture note the exhaust front pipe its not continous as in the 250/270 theres 2 joints level with the barrel.on a125 plus u could try this.http://www.whomademybike.com/ Edited October 17, 2014 by bilks Quote Link to comment Share on other sites More sharing options...

burns1989 Posted October 18, 2014 Author Report Share Posted October 18, 2014 Well the power isue could just be me as im used to my mx bike rm 250 and that lays down the power Pritty hard at 50 brake but I gues a trials bike is less power but more torque. Or could it be down to how it's been geared down as 1st is all most like walking pace . Does any one know the standard sprocket sizes .chears ian Quote Link to comment Share on other sites More sharing options...
