March 2, 201610 yr Hello all.... Been getting this Rev 3 back to good working order. Cannot conclusively find out what size motor this is.. I think it's a 125 but ????
March 2, 201610 yr Normally they put a sign on the side of the cilinders? Dont know if beta does this though. Also the frame code should help out. Edited March 2, 201610 yr by crazybond700
March 2, 201610 yr If you remove the exhaust pipe you should be able to get a sufficently accurate measure on the bore size. Failing which take the head off and measure it. I can't see the picture on the system I am on at the moment.
March 2, 201610 yr Are you in the UK ? If so call Beta UK quote frame and engine numbers they will have all relevant information. I think it may be a 2002 model by the colours.
March 2, 201610 yr It is definatley a 2001 model, I had a brand new one back in the day, not sure on cc but probably a 250/270
March 2, 201610 yr Yeap, a 2001, I had one too, though not many got sold that year in the UK due to the Foot & Mouth outbreak. If you measure the bore/piston: 125 pistons are 54mm 200 pistons are 64mm 250 pistons are 72.5mm 270 pistons are 76mm 2000 models were black/red with USD forks and air box cover on the left side. 2001 models were blue with conventional forks (as were all those since) and the air box cover on the left side. 2002 models were maroon and the air box cover in the seat (as were all those since). 2003 models were yellow. 2004 models were orange 2005 models were red/grey 2006 models were black/red/silver 2007 models were red with fat bars (4t black & red) 2008 models were red/white with fat bars(4t black & red) Edited March 2, 201610 yr by goudrons
March 2, 201610 yr Author Not in the UK unfortunately... Trials riding (just like supermoto) is not nearly as popular in the US which makes it much more difficult to find parts/information. Thanks to all of you for your info!
March 2, 201610 yr The 125 front pipe has normally 2 weld rings on the front pipe welded together because of the reduction in size 125 cc.roughly level with the barrel .The 250/270 front pipe is 1 piece.http://www.betausa.com/node/751 Edited March 2, 201610 yr by bilks
