I had a 2016 sduro allmtn rc. Same frame. The 2017 5.0 has a tougher fork and nice equpiment. The frame is quite short by todays standards. I removed the large chain ring and front shift. Swapped the small ring for a narrow/wide. Got a shorter stem. Got a Sunrace 11-40 cassette. And installed a single offset bushing, that made descents feel safer.
The Yamaha pw is fine as long as you keep the cadence at about 70.
Didn't have much time when I wrote this yesterday, so I'll elaborate a bit now. The old sduro allmtn frame geometry is a bit dated, and sort of the oposite of the modern long-low-slack trend. I'm 181/5'11 and had a Large. I only used the bike for trails and didn't need the large front chain ring, but for an allround bike you may want to keep it. The lowest gear is 32-36, and that isn't that low. So I swapped the cassette for an 11-40 Sunrace. If you get a goatlink for the rear derailleur you can probably go 11-42 or even 11-46.
The single 22,2mm offset bushing dropped the head angle by half a degree, and lowered to bottom bracket a few mm's. I swapped the 70mm stem for one that was 10 or 20mm shorter, don't remember. That really transformed the bike from a long travel allrounder to a quite capable descender. So if you want a capable trail bike, I reccommend looking into this. Cheap and quite easy to do
As I said, the Yamaha PW doesn't handle high cadence very well. From just above 60 to just above 70 rpm it's strong and can be ridden without much effort. I was used to a higher pedal frequency and had to change my riding style a bit.
I just reserved the same bike, it should be with me soon. I'm aware of the shortfalls: 400w/h battery and the brakes aren't the best. The rest should work nicely. It has a single sprocket up front, which is fine by me. I'm intrigued by the Yamaha motor as it seems to suit me with zero point crank support. Biggest worry is the battery, really. My thinking is that even with an extra battery and top brakes I'm still saving a massive chunk Vs other bikes and I'll customize as I go along. Thanks for reading
Bike has arrived. It was a bit dirty but it looks like it's brand new. I reckon it's not been used more than a few times. I am charging the battery and can't wait for the working day to finish to have a blast.
I fitted a dropper post and ordered a frame cable inlet for it.
