I’ve built a few bikes in the past (mainly honda’s) This one is a 2012 CRF250R, 2001...

It’s been a while, will be cutting / welding the frame this week with an local engineering company !! Fits in the oem Frame but just doesn’t work. So will need to cut the frame a lot to raise the “Y”, make some spacers for the swing arm, and hopefully we get the engine sitting correctly...

Will be using Bridgestone tyres, that’s what I sell! Will be using the X20 series front and rear, with a 110/90-19 rear, stock size but is my preferred tyre size for this chassis. New hardware to mount the discs and sprocket aswell I’m pretty impressed with the new range from bolt hardware, very comprehensive and priced right. Couldn’t...

It’s not prefect but Came up miles better than before, plus took me less than an hour to do them...

Lol “pala must do something”, give me a break dude not all of us want a nani holding ours hands through life. We’ve already got the government regulating the living hell out of everything, the last thing anyone needs is more rules riding your dirtbike. Dude went for it on an 06 crf450, much respect for that send!
