Hey, I'm looking for some advice on whether or not it's a good idea to replace the front brake on an '83 XL600R. It's a disc brake but it's fairly tiny in comparison to most more modern bikes. I'll get round to getting the exact specifications but it can't be any bigger than the disc on my other bike, a DT175. I know it's an older trail bike and wasn't intended to be fitted with anything ridiculously large but if anyone had any idea's as to a suitable, slightly more powerful setup it'd be appreciated. Also, will this kind of modification cause any radical change in the handling/the reaction I'm going to get from the suspension/etc, to the point where the swap isn't going to be worth it/safe? Has anyone else done this kind of swap before and how much difference is there going to be in the brake caliper bolt position/how the different disc is going to be fitted/are there going to be any issues fitting a different reservoir? Cheers.
