  • Depends how u ride tbh.... short journeys would be fine long distance is a no no

  • Just not worth the trouble.

  • Defiantly 4T I do a minimum of 100 miles a week and I prefer the sound of a beefy 4T than a tinny 2T, just a time and place for them but was just trynna work out whether it would be easier to just swap out the engine

  • I'm torn between buying a Yamaha R1 or a Ninja 500 for the motor in my grom. I'm the senior fabricator and machinist where I work so either is feasible. Haven't decided which bike I want to die on yet, lol.

  • I think everyone will agree here a 1000 Grom would be EPIC so R1

  • Lol. No 1000 in the grom!

  • My buddy put a gsxr 600 motor in his 4 wheeler, so anything can be done.

  • Full gsxr body work, I didn't want to ride it, lol.

  • I meant by the way I ride a R1 or swap a Ninja 500 motor, sorry for the confusion.

  • 100 miles a week on a race bred engine = lots and lots of trouble just have a look at the maintenance schedule for the crf, if you wanna use it daily bbk is the way to go of its just a toy yeah swap something crazy
