I'm running both mate... Rapido with reedvalve in my Red & White S2, and an RT in my GP. Both I have fitted with 60mm cranks.

Have a lot of confidence in both.....

All I can say is that the BGM RT went together with absolutely no fettling at all, whilst the Rapido took a lot of work to get the compression correct....

As you said the RT is very well made. I ran mine with a 26 Delly and have just fitted a 28 and whilst not got the jetting sorted yet it does feel quicker. I ride mine with confidence having done a few Pistons :oops: like you in the last year. 300 miles running in only..

How much would Martin charge to bore your existing barrel to 225, and give it a 'proper' stage 4 tune?

I think he wants something a bit cheaper last time I looked honda 67mm pistons were going for £150 and thats if you could find one I gave up after a year and didnt want to pay for the MBD one
We sleep soundly in our beds because rough men stand ready in the night to visit violence on those who would do us harm
