A motorcycle includes a swing arm defining a drive member aperture through which a flexible drive member extends. During normal operation of the motorcycle, the drive member and swing arm are interlocked due to a portion of the drive member being captured in the drive member aperture. A portion of the swing arm is removable from the rest of the swing arm to open the drive member aperture and permit removal of the drive member as a continuous unbroken loop without the need to drop the motorcycle's transmission.

The apparatus of claim 14, wherein the bladder is expandable in a radial direction. 17. The apparatus of claim 16, wherein the bladder is attached to the tubular body member. 18. The apparatus of claim 17, wherein the bladder has an upper end and a lower end, and both the upper end and the lower end are connected to the tubular body member. 19. The apparatus of claim 18, wherein the second tubular body segment comprises an upper packer head and a lower packer head, and the bladder upper end is connected to the upper packer head and the bladder lower end is connected to the lower packer head. 20. The apparatus of claim 19, wherein the conduit extends through the upper packer head and communicates between the exterior of the first segment of the tubular body member and the interior of the bladder. 21. The apparatus of claim 19, further comprising a third segment of the tubular body member, wherein the conduit extends through the upper and lower packer heads and communicates between the exterior of the first and third segments of the tubular body member and the interior of the bladder. 22. The apparatus of claim 14, wherein at least one aperture in the second segment of the tubular body member provides fluid communication between the longitudinal bore of the tubular body member and the interior of the bladder. 23. The apparatus of claim 22, wherein the at least one aperture allows fluid communication but restricts particulate communication. 24. The apparatus of claim 14, wherein the conduit enables communication between the exterior of the first segment of the tubular body member and the interior of the bladder. 25. The apparatus of claim 14, further comprising a third segment of the tubular body member wherein the conduit enables communication between the exterior of the first and third segments with the interior of the bladder. 26. The apparatus of claim 14, wherein the bladder comprises a material that allows the passage of fluid but restricts the passage of particulates. 27. A wellbore isolation tool comprising: a tubular body having a longitudinal bore therethrough; an expandable bladder attached to the tubular body; a conduit providing communication between the expandable bladder and the exterior of the tubular body; and wherein the conduit allows a gravel laden slurry to enter and expand the bladder. 28. The tool of claim 27, wherein the conduit comprises a check valve that restricts reverse flow. 29. The tool of claim 28, wherein the bladder has an upper end and a lower end, and both the upper end and the lower end are connected to the tubular body. 30. The tool of claim 29, wherein the expandable bladder encloses a portion of the tubular body comprising at least one aperture, the at least one aperture assisting the dehydration of the gravel laden slurry by allowing fluid flow from the gravel laden slurry within the expandable bladder through the at least one aperture in the tubular body and into the longitudinal bore of the tubular body. 31. The apparatus of claim 30, wherein the at least one aperture allows fluid communication but restricts particulate communication. 32. An apparatus comprising: a tubular body member having first, second and third segments, the first and third segments being on opposite ends of the second segment, each segment having an exterior and a longitudinal bore extending therethrough; a bladder surrounding the second segment of the tubular body, the bladder having a wall and an interior; a conduit located adjacent the first and third segments and extending through the wall of the bladder; and wherein the conduit allows a gravel laden slurry to enter and expand the bladder. 33. The apparatus of claim 32, wherein the conduit enables communication between the exterior of the first and third segments with the interior of the bladder. 34. The apparatus of claim 33, wherein during a gravel pack completion of a wellb ore the conduit allows gravel laden slurry to communicate between the exterior of the first and third segments and the interior of the bladder. 35. The apparatus of claim 34, wherein the conduit comprises a check valve that restricts reverse flow. 36. The apparatus of claim 32, wherein the second segment of the tubular body comprises at least one aperture that assists the dehydration of the gravel laden slurry within the bladder. 37. The apparatus of claim 36, wherein the at least one aperture allows fluid communication but restricts particulate communication. 38. The apparatus of claim 37, wherein the bladder is capable of radial expansion upon being filled with gravel. 39. The apparatus of claim 38, wherein the expanded bladder forms a seal between the tubular body and the wellbore wall. 40. A method of sealing an annulus in a well, comprising: expanding an inflatable element with a gravel laden slurry, the inflatable element comprising a passageway communicating between an exterior and an interior of the inflatable element and wherein the passageway comprises a check valve that restricts reverse flow; the inflatable element is connected to a sand screen and the inflatable element is inflated with the gravel laden slurry during a gravel packing of the well; the gravel packing of the well comprises pumping the gravel laden slurry into the well wherein at least a portion of the gravel laden slurry passes through the passageway and enters the inflatable element. 41. The method of claim 40, wherein the gravel laden slurry dehydrates leaving the inflatable element in an inflated condition filled with gravel. 42. The method of claim 41, comprising more than one inflatable elements and at least one of the inflatable elements is inflated with a gravel laden slurry. 43. The method of claim 41, wherein the inflatable element seals the annulus of the well and isolates a first zone from a second zone. 44. The method of claim 41, wherein the inflatable element is used to seal off lower depths in the well. 45. A method of completing a well, comprising: providing a sand screen completion having at least one inflatable element therein; gravel packing at least a portion of the well with a gravel slurry; and inflating the inflatable element with the gravel slurry. 46. The method of claim 45, wherein the inflatable element comprises a passageway communicating between an exterior and an interior of the inflatable element. 47. The method of claim 46, wherein the passageway comprises a check valve that restricts reverse flow. 48. The method of claim 45, wherein the inflatable element is connected to a sand screen and the inflatable element is inflated with the gravel slurry during a gravel packing of the well. 49. The method of claim 48, wherein the gravel packing of the well comprises pumping the gravel slurry into the well wherein at least a portion of the gravel slurry passes through the passageway and enters the inflatable element. 50. The method of claim 49, wherein the gravel slurry dehydrates, leaving the inflatable element in an inflated condition filled with gravel. 51. The method of claim 49, comprising more than one inflatable elements and at least one of the inflatable elements is inflated with a gravel slurry. 52. The method of claim 49, wherein the inflatable element seals the annulus of the well and isolates a first zone from a second zone. 53. The method of claim 49, wherein the inflatable element is used to seal off lower depths in the well. 54. A method of completing a wellbore comprising: providing an apparatus comprising: a tubular body member; a bladder; and a conduit; positioning the apparatus within the wellbore; pumping a gravel laden slurry into the wellbore, wherein at least a portion of the slurry passes through the conduit into the bladder; wherein the bladder expands and forms a seal between the tubular body and a wellbore wall; wherein the tubular body comprises at least one aperture that assists
