I have interest in getting a DS(Dual Sport) bike. I used to own a 2000 Suzuki DR650SE which was a lot of fun as a primarily street ridden bike. I did 3 DS rides with it and learned how lacking it was for DS'ing........in it's stock configuration. It's gone now and I have the DS bug again! I'd like to hear from folks in the "know" about 'R' and 'L' gearbox ratios.......I don't have the factory shop manuals or I'd be able to figure it out on my own. Does the 'L' have the same internal gearing as the 'R' and just a different secondary gearing(sprockets)?? Also.......is basic frame geometry and wheelbase shared between the 'R' and the 'L' or are there documentable(service manuals) differences? I DO understand that the frame on the 'R' is aluminum and re-designed....... I also read(trying to do some homework) that the 'R' has a larger rear axle than the 'L'. Just interested in hearing about maintenance issues and preceiveable differences that might apply to Dual Sport applications. I know about the power differences and the DOT stuff.....luckily I live in AZ where folks can easily get a BRP tagged. Thanks in advance for any info that will help in my decision making. I did get to ride a 'R'(unplugged) the other day and that bike had some 'nads' compared to my prior DR(stock) experience. Happy 'XPLRN'
