I've been using RB for years & every time I try something else, I'm disapointed & go back to RB. If your track is small the S5 is my favorite. For big tracks both the WS7III & the C6 are great. I like the C6 with a 2045 pipe the best on big tracks. If your on a budget & have a medium to large track I recomend the regular S7. For me If you told me I could only buy 1 motor & had to run it on every track I would pick the regular S7. These motors last a long time if you take care of them & keep them tunned properly. They are easy to tune (especially the S motors). Please, if you get an RB, run a good pipe on it. Pipes make all the difference on performance. For me, I like the 2045 pipe for racing with the C6. Great power & fantastic fuel economy. For track bashing & practice I like the 2020 pipe but it has worse fuel economy.

I'm not an employee or affiliated with RB Concepts in any way.
