Re: Backrest or a top case for 1979 R45

it makes sense in that scenario to move to a 38 mm Brembo what ever else is done. Thanks for the information. Because your reply didn't include a take on the number of discs, I take it as single disc would still be adequate for two up driving given that the driving habits are not sporty, and that t...

Re: Backrest or a top case for 1979 R45

The extra power may highlight the braking issue unless they too have been upgraded. We're clearly diverting from the original topic, but I take it as we're both guilty and open to it. ;) I can find retrofit sets to upgrade brakes to a dual disc setup. But I've not seen too many posts nor videos abo...

Re: Backrest or a top case for 1979 R45

Thanks for the considerations - appreciate your useful advise. What I know of the R45 I'm considering is that it has been upgraded with "800cc parts" but due to the technical reasons, it ends up as 700cc engine. Also, carburetors have been upgraded, as well as the drive train for better ge...
